Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665938, here are decompositions:

  • 5 + 8665933 = 8665938
  • 7 + 8665931 = 8665938
  • 41 + 8665897 = 8665938
  • 89 + 8665849 = 8665938
  • 139 + 8665799 = 8665938
  • 271 + 8665667 = 8665938
  • 367 + 8665571 = 8665938
  • 397 + 8665541 = 8665938

Showing the first eight; more decompositions exist.
