Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535658, here are decompositions:

  • 19 + 31535639 = 31535658
  • 67 + 31535591 = 31535658
  • 107 + 31535551 = 31535658
  • 109 + 31535549 = 31535658
  • 191 + 31535467 = 31535658
  • 229 + 31535429 = 31535658
  • 239 + 31535419 = 31535658
  • 241 + 31535417 = 31535658

Showing the first eight; more decompositions exist.
