Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164528, here are decompositions:

  • 79 + 164449 = 164528
  • 97 + 164431 = 164528
  • 109 + 164419 = 164528
  • 151 + 164377 = 164528
  • 157 + 164371 = 164528
  • 229 + 164299 = 164528
  • 277 + 164251 = 164528
  • 337 + 164191 = 164528

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 164,528 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 164528 first appears in π at position 173,083 of the decimal expansion (the 173,083ordinal-suffix:rd 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.
