Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535718, here are decompositions:

  • 37 + 31535681 = 31535718
  • 47 + 31535671 = 31535718
  • 61 + 31535657 = 31535718
  • 79 + 31535639 = 31535718
  • 127 + 31535591 = 31535718
  • 167 + 31535551 = 31535718
  • 251 + 31535467 = 31535718
  • 307 + 31535411 = 31535718

Showing the first eight; more decompositions exist.
