Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525740, here are decompositions:

  • 13 + 525727 = 525740
  • 31 + 525709 = 525740
  • 43 + 525697 = 525740
  • 157 + 525583 = 525740
  • 199 + 525541 = 525740
  • 211 + 525529 = 525740
  • 223 + 525517 = 525740
  • 283 + 525457 = 525740

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 525,740 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 525740 first appears in π at position 733,585 of the decimal expansion (the 733,585ordinal-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.
