Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626810, here are decompositions:

  • 47 + 8626763 = 8626810
  • 113 + 8626697 = 8626810
  • 167 + 8626643 = 8626810
  • 197 + 8626613 = 8626810
  • 233 + 8626577 = 8626810
  • 281 + 8626529 = 8626810
  • 293 + 8626517 = 8626810
  • 317 + 8626493 = 8626810

Showing the first eight; more decompositions exist.
