Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149186, here are decompositions:

  • 3 + 149183 = 149186
  • 13 + 149173 = 149186
  • 43 + 149143 = 149186
  • 67 + 149119 = 149186
  • 73 + 149113 = 149186
  • 109 + 149077 = 149186
  • 127 + 149059 = 149186
  • 229 + 148957 = 149186

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 149,186 and was likely granted around 1873.

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