Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545526, here are decompositions:

  • 197 + 31545329 = 31545526
  • 227 + 31545299 = 31545526
  • 239 + 31545287 = 31545526
  • 293 + 31545233 = 31545526
  • 443 + 31545083 = 31545526
  • 503 + 31545023 = 31545526
  • 557 + 31544969 = 31545526
  • 563 + 31544963 = 31545526

Showing the first eight; more decompositions exist.
