Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164480, here are decompositions:

  • 3 + 164477 = 164480
  • 31 + 164449 = 164480
  • 37 + 164443 = 164480
  • 61 + 164419 = 164480
  • 67 + 164413 = 164480
  • 103 + 164377 = 164480
  • 109 + 164371 = 164480
  • 139 + 164341 = 164480

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 164,480 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 164480 first appears in π at position 496,974 of the decimal expansion (the 496,974ordinal-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.
