Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627460, here are decompositions:

  • 103 + 31627357 = 31627460
  • 127 + 31627333 = 31627460
  • 157 + 31627303 = 31627460
  • 199 + 31627261 = 31627460
  • 211 + 31627249 = 31627460
  • 223 + 31627237 = 31627460
  • 409 + 31627051 = 31627460
  • 433 + 31627027 = 31627460

Showing the first eight; more decompositions exist.
