Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161084, here are decompositions:

  • 13 + 161071 = 161084
  • 31 + 161053 = 161084
  • 37 + 161047 = 161084
  • 67 + 161017 = 161084
  • 103 + 160981 = 161084
  • 151 + 160933 = 161084
  • 181 + 160903 = 161084
  • 223 + 160861 = 161084

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 161,084 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 161084 first appears in π at position 448,471 of the decimal expansion (the 448,471ordinal-suffix:st 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.
