Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638982, here are decompositions:

  • 31 + 8638951 = 8638982
  • 73 + 8638909 = 8638982
  • 139 + 8638843 = 8638982
  • 349 + 8638633 = 8638982
  • 439 + 8638543 = 8638982
  • 571 + 8638411 = 8638982
  • 601 + 8638381 = 8638982
  • 643 + 8638339 = 8638982

Showing the first eight; more decompositions exist.
