Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525286, here are decompositions:

  • 29 + 525257 = 525286
  • 149 + 525137 = 525286
  • 257 + 525029 = 525286
  • 269 + 525017 = 525286
  • 317 + 524969 = 525286
  • 347 + 524939 = 525286
  • 353 + 524933 = 525286
  • 617 + 524669 = 525286

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 525,286 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 525286 first appears in π at position 404,778 of the decimal expansion (the 404,778ordinal-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.
