Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987522, here are decompositions:

  • 13 + 987509 = 987522
  • 31 + 987491 = 987522
  • 59 + 987463 = 987522
  • 89 + 987433 = 987522
  • 131 + 987391 = 987522
  • 139 + 987383 = 987522
  • 223 + 987299 = 987522
  • 229 + 987293 = 987522

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 987,522 and was likely granted around 1911.

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

Position in π

The digit sequence 987522 first appears in π at position 462,985 of the decimal expansion (the 462,985ordinal-suffix:th 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.
