Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103520, here are decompositions:

  • 37 + 103483 = 103520
  • 97 + 103423 = 103520
  • 127 + 103393 = 103520
  • 163 + 103357 = 103520
  • 229 + 103291 = 103520
  • 283 + 103237 = 103520
  • 337 + 103183 = 103520
  • 349 + 103171 = 103520

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 103,520 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 103520 first appears in π at position 392,937 of the decimal expansion (the 392,937ordinal-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.
