Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545394, here are decompositions:

  • 3 + 31545391 = 31545394
  • 71 + 31545323 = 31545394
  • 107 + 31545287 = 31545394
  • 173 + 31545221 = 31545394
  • 311 + 31545083 = 31545394
  • 431 + 31544963 = 31545394
  • 677 + 31544717 = 31545394
  • 821 + 31544573 = 31545394

Showing the first eight; more decompositions exist.
