Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626828, here are decompositions:

  • 5 + 8626823 = 8626828
  • 17 + 8626811 = 8626828
  • 131 + 8626697 = 8626828
  • 137 + 8626691 = 8626828
  • 251 + 8626577 = 8626828
  • 311 + 8626517 = 8626828
  • 359 + 8626469 = 8626828
  • 479 + 8626349 = 8626828

Showing the first eight; more decompositions exist.
