Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528940, here are decompositions:

  • 11 + 528929 = 528940
  • 29 + 528911 = 528940
  • 59 + 528881 = 528940
  • 107 + 528833 = 528940
  • 149 + 528791 = 528940
  • 233 + 528707 = 528940
  • 281 + 528659 = 528940
  • 311 + 528629 = 528940

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 528,940 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 528940 first appears in π at position 291,051 of the decimal expansion (the 291,051ordinal-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.
