Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545354, here are decompositions:

  • 11 + 31545343 = 31545354
  • 23 + 31545331 = 31545354
  • 31 + 31545323 = 31545354
  • 37 + 31545317 = 31545354
  • 67 + 31545287 = 31545354
  • 163 + 31545191 = 31545354
  • 173 + 31545181 = 31545354
  • 257 + 31545097 = 31545354

Showing the first eight; more decompositions exist.
