Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535610, here are decompositions:

  • 17 + 31535593 = 31535610
  • 19 + 31535591 = 31535610
  • 59 + 31535551 = 31535610
  • 61 + 31535549 = 31535610
  • 107 + 31535503 = 31535610
  • 181 + 31535429 = 31535610
  • 191 + 31535419 = 31535610
  • 193 + 31535417 = 31535610

Showing the first eight; more decompositions exist.
