Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525512, here are decompositions:

  • 19 + 525493 = 525512
  • 73 + 525439 = 525512
  • 79 + 525433 = 525512
  • 103 + 525409 = 525512
  • 139 + 525373 = 525512
  • 151 + 525361 = 525512
  • 199 + 525313 = 525512
  • 271 + 525241 = 525512

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 525,512 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 525512 first appears in π at position 655,206 of the decimal expansion (the 655,206ordinal-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.
