Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535634, here are decompositions:

  • 41 + 31535593 = 31535634
  • 43 + 31535591 = 31535634
  • 83 + 31535551 = 31535634
  • 131 + 31535503 = 31535634
  • 167 + 31535467 = 31535634
  • 211 + 31535423 = 31535634
  • 223 + 31535411 = 31535634
  • 257 + 31535377 = 31535634

Showing the first eight; more decompositions exist.
