Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638264, here are decompositions:

  • 17 + 8638247 = 8638264
  • 23 + 8638241 = 8638264
  • 113 + 8638151 = 8638264
  • 197 + 8638067 = 8638264
  • 311 + 8637953 = 8638264
  • 443 + 8637821 = 8638264
  • 563 + 8637701 = 8638264
  • 647 + 8637617 = 8638264

Showing the first eight; more decompositions exist.
