Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545094, here are decompositions:

  • 3 + 31545091 = 31545094
  • 11 + 31545083 = 31545094
  • 71 + 31545023 = 31545094
  • 131 + 31544963 = 31545094
  • 311 + 31544783 = 31545094
  • 521 + 31544573 = 31545094
  • 563 + 31544531 = 31545094
  • 677 + 31544417 = 31545094

Showing the first eight; more decompositions exist.
