Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672940, here are decompositions:

  • 7 + 8672933 = 8672940
  • 13 + 8672927 = 8672940
  • 43 + 8672897 = 8672940
  • 71 + 8672869 = 8672940
  • 79 + 8672861 = 8672940
  • 109 + 8672831 = 8672940
  • 139 + 8672801 = 8672940
  • 149 + 8672791 = 8672940

Showing the first eight; more decompositions exist.
