Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637748, here are decompositions:

  • 47 + 8637701 = 8637748
  • 107 + 8637641 = 8637748
  • 131 + 8637617 = 8637748
  • 137 + 8637611 = 8637748
  • 227 + 8637521 = 8637748
  • 239 + 8637509 = 8637748
  • 257 + 8637491 = 8637748
  • 281 + 8637467 = 8637748

Showing the first eight; more decompositions exist.
