Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638006, here are decompositions:

  • 53 + 8637953 = 8638006
  • 137 + 8637869 = 8638006
  • 227 + 8637779 = 8638006
  • 257 + 8637749 = 8638006
  • 389 + 8637617 = 8638006
  • 479 + 8637527 = 8638006
  • 557 + 8637449 = 8638006
  • 683 + 8637323 = 8638006

Showing the first eight; more decompositions exist.
