Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619602, here are decompositions:

  • 41 + 31619561 = 31619602
  • 59 + 31619543 = 31619602
  • 71 + 31619531 = 31619602
  • 83 + 31619519 = 31619602
  • 101 + 31619501 = 31619602
  • 389 + 31619213 = 31619602
  • 419 + 31619183 = 31619602
  • 431 + 31619171 = 31619602

Showing the first eight; more decompositions exist.
