Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162838, here are decompositions:

  • 17 + 162821 = 162838
  • 47 + 162791 = 162838
  • 59 + 162779 = 162838
  • 89 + 162749 = 162838
  • 107 + 162731 = 162838
  • 167 + 162671 = 162838
  • 197 + 162641 = 162838
  • 227 + 162611 = 162838

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 162,838 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 162838 first appears in π at position 91,793 of the decimal expansion (the 91,793ordinal-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.
