Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525040, here are decompositions:

  • 11 + 525029 = 525040
  • 23 + 525017 = 525040
  • 41 + 524999 = 525040
  • 59 + 524981 = 525040
  • 71 + 524969 = 525040
  • 83 + 524957 = 525040
  • 101 + 524939 = 525040
  • 107 + 524933 = 525040

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 525,040 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 525040 first appears in π at position 704,456 of the decimal expansion (the 704,456ordinal-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.
