Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523988, here are decompositions:

  • 19 + 523969 = 523988
  • 61 + 523927 = 523988
  • 211 + 523777 = 523988
  • 229 + 523759 = 523988
  • 271 + 523717 = 523988
  • 307 + 523681 = 523988
  • 331 + 523657 = 523988
  • 349 + 523639 = 523988

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 523,988 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 523988 first appears in π at position 820,543 of the decimal expansion (the 820,543ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
