Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646608, here are decompositions:

  • 37 + 8646571 = 8646608
  • 79 + 8646529 = 8646608
  • 97 + 8646511 = 8646608
  • 151 + 8646457 = 8646608
  • 331 + 8646277 = 8646608
  • 349 + 8646259 = 8646608
  • 547 + 8646061 = 8646608
  • 709 + 8645899 = 8646608

Showing the first eight; more decompositions exist.
