Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757986, here are decompositions:

  • 43 + 8757943 = 8757986
  • 67 + 8757919 = 8757986
  • 109 + 8757877 = 8757986
  • 157 + 8757829 = 8757986
  • 229 + 8757757 = 8757986
  • 463 + 8757523 = 8757986
  • 499 + 8757487 = 8757986
  • 577 + 8757409 = 8757986

Showing the first eight; more decompositions exist.
