Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637900, here are decompositions:

  • 31 + 8637869 = 8637900
  • 53 + 8637847 = 8637900
  • 71 + 8637829 = 8637900
  • 79 + 8637821 = 8637900
  • 109 + 8637791 = 8637900
  • 113 + 8637787 = 8637900
  • 151 + 8637749 = 8637900
  • 199 + 8637701 = 8637900

Showing the first eight; more decompositions exist.
