Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160978, here are decompositions:

  • 11 + 160967 = 160978
  • 71 + 160907 = 160978
  • 101 + 160877 = 160978
  • 137 + 160841 = 160978
  • 149 + 160829 = 160978
  • 197 + 160781 = 160978
  • 227 + 160751 = 160978
  • 239 + 160739 = 160978

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 160,978 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 160978 first appears in π at position 838,083 of the decimal expansion (the 838,083ordinal-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.
