Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162660, here are decompositions:

  • 11 + 162649 = 162660
  • 19 + 162641 = 162660
  • 31 + 162629 = 162660
  • 37 + 162623 = 162660
  • 59 + 162601 = 162660
  • 67 + 162593 = 162660
  • 83 + 162577 = 162660
  • 97 + 162563 = 162660

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 162,660 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 162660 first appears in π at position 603,506 of the decimal expansion (the 603,506ordinal-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.
