Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164290, here are decompositions:

  • 11 + 164279 = 164290
  • 23 + 164267 = 164290
  • 41 + 164249 = 164290
  • 59 + 164231 = 164290
  • 89 + 164201 = 164290
  • 107 + 164183 = 164290
  • 173 + 164117 = 164290
  • 197 + 164093 = 164290

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 164,290 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 164290 first appears in π at position 217,418 of the decimal expansion (the 217,418ordinal-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.
