Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657922, here are decompositions:

  • 19 + 8657903 = 8657922
  • 41 + 8657881 = 8657922
  • 71 + 8657851 = 8657922
  • 73 + 8657849 = 8657922
  • 89 + 8657833 = 8657922
  • 139 + 8657783 = 8657922
  • 151 + 8657771 = 8657922
  • 191 + 8657731 = 8657922

Showing the first eight; more decompositions exist.
