Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450504, here are decompositions:

  • 17 + 31450487 = 31450504
  • 53 + 31450451 = 31450504
  • 83 + 31450421 = 31450504
  • 191 + 31450313 = 31450504
  • 233 + 31450271 = 31450504
  • 257 + 31450247 = 31450504
  • 401 + 31450103 = 31450504
  • 443 + 31450061 = 31450504

Showing the first eight; more decompositions exist.
