Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164470, here are decompositions:

  • 23 + 164447 = 164470
  • 41 + 164429 = 164470
  • 83 + 164387 = 164470
  • 107 + 164363 = 164470
  • 113 + 164357 = 164470
  • 149 + 164321 = 164470
  • 179 + 164291 = 164470
  • 191 + 164279 = 164470

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 164,470 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 164470 first appears in π at position 3,370 of the decimal expansion (the 3,370ordinal-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.
