Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535746, here are decompositions:

  • 5 + 31535741 = 31535746
  • 29 + 31535717 = 31535746
  • 89 + 31535657 = 31535746
  • 107 + 31535639 = 31535746
  • 113 + 31535633 = 31535746
  • 197 + 31535549 = 31535746
  • 317 + 31535429 = 31535746
  • 419 + 31535327 = 31535746

Showing the first eight; more decompositions exist.
