Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164198, here are decompositions:

  • 7 + 164191 = 164198
  • 109 + 164089 = 164198
  • 127 + 164071 = 164198
  • 211 + 163987 = 164198
  • 271 + 163927 = 164198
  • 337 + 163861 = 164198
  • 379 + 163819 = 164198
  • 409 + 163789 = 164198

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 164,198 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 164198 first appears in π at position 178,254 of the decimal expansion (the 178,254ordinal-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.
