Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162738, here are decompositions:

  • 7 + 162731 = 162738
  • 11 + 162727 = 162738
  • 29 + 162709 = 162738
  • 47 + 162691 = 162738
  • 61 + 162677 = 162738
  • 67 + 162671 = 162738
  • 89 + 162649 = 162738
  • 97 + 162641 = 162738

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 162,738 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 162738 first appears in π at position 150,970 of the decimal expansion (the 150,970ordinal-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.
