Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512180, here are decompositions:

  • 13 + 512167 = 512180
  • 43 + 512137 = 512180
  • 79 + 512101 = 512180
  • 241 + 511939 = 512180
  • 271 + 511909 = 512180
  • 283 + 511897 = 512180
  • 307 + 511873 = 512180
  • 313 + 511867 = 512180

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 512,180 and was likely granted around 1893.

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

Position in π

The digit sequence 512180 first appears in π at position 508,445 of the decimal expansion (the 508,445ordinal-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.
