Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525988, here are decompositions:

  • 5 + 525983 = 525988
  • 41 + 525947 = 525988
  • 101 + 525887 = 525988
  • 149 + 525839 = 525988
  • 179 + 525809 = 525988
  • 257 + 525731 = 525988
  • 269 + 525719 = 525988
  • 311 + 525677 = 525988

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 525,988 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 525988 first appears in π at position 884,731 of the decimal expansion (the 884,731ordinal-suffix:st 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.
