Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529640, here are decompositions:

  • 3 + 529637 = 529640
  • 37 + 529603 = 529640
  • 61 + 529579 = 529640
  • 109 + 529531 = 529640
  • 127 + 529513 = 529640
  • 151 + 529489 = 529640
  • 229 + 529411 = 529640
  • 283 + 529357 = 529640

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 529,640 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 529640 first appears in π at position 762,075 of the decimal expansion (the 762,075ordinal-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.
