Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677640, here are decompositions:

  • 157 + 8677483 = 8677640
  • 163 + 8677477 = 8677640
  • 241 + 8677399 = 8677640
  • 373 + 8677267 = 8677640
  • 379 + 8677261 = 8677640
  • 613 + 8677027 = 8677640
  • 691 + 8676949 = 8677640
  • 757 + 8676883 = 8677640

Showing the first eight; more decompositions exist.
