Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637946, here are decompositions:

  • 3 + 8637943 = 8637946
  • 17 + 8637929 = 8637946
  • 167 + 8637779 = 8637946
  • 197 + 8637749 = 8637946
  • 419 + 8637527 = 8637946
  • 479 + 8637467 = 8637946
  • 683 + 8637263 = 8637946
  • 719 + 8637227 = 8637946

Showing the first eight; more decompositions exist.
