Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535766, here are decompositions:

  • 13 + 31535753 = 31535766
  • 19 + 31535747 = 31535766
  • 109 + 31535657 = 31535766
  • 127 + 31535639 = 31535766
  • 173 + 31535593 = 31535766
  • 263 + 31535503 = 31535766
  • 337 + 31535429 = 31535766
  • 347 + 31535419 = 31535766

Showing the first eight; more decompositions exist.
