Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164512, here are decompositions:

  • 41 + 164471 = 164512
  • 83 + 164429 = 164512
  • 149 + 164363 = 164512
  • 191 + 164321 = 164512
  • 233 + 164279 = 164512
  • 263 + 164249 = 164512
  • 281 + 164231 = 164512
  • 311 + 164201 = 164512

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 164,512 and was likely granted around 1874.

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

Position in π

The digit sequence 164512 first appears in π at position 737,227 of the decimal expansion (the 737,227ordinal-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.
