Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149198, here are decompositions:

  • 37 + 149161 = 149198
  • 79 + 149119 = 149198
  • 97 + 149101 = 149198
  • 139 + 149059 = 149198
  • 241 + 148957 = 149198
  • 271 + 148927 = 149198
  • 277 + 148921 = 149198
  • 307 + 148891 = 149198

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 149,198 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 149198 first appears in π at position 728,870 of the decimal expansion (the 728,870ordinal-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.
