Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539064, here are decompositions:

  • 3 + 31539061 = 31539064
  • 17 + 31539047 = 31539064
  • 113 + 31538951 = 31539064
  • 257 + 31538807 = 31539064
  • 311 + 31538753 = 31539064
  • 353 + 31538711 = 31539064
  • 503 + 31538561 = 31539064
  • 587 + 31538477 = 31539064

Showing the first eight; more decompositions exist.
