Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674128, here are decompositions:

  • 19 + 8674109 = 8674128
  • 37 + 8674091 = 8674128
  • 41 + 8674087 = 8674128
  • 59 + 8674069 = 8674128
  • 79 + 8674049 = 8674128
  • 131 + 8673997 = 8674128
  • 139 + 8673989 = 8674128
  • 227 + 8673901 = 8674128

Showing the first eight; more decompositions exist.
