Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626742, here are decompositions:

  • 43 + 8626699 = 8626742
  • 73 + 8626669 = 8626742
  • 139 + 8626603 = 8626742
  • 193 + 8626549 = 8626742
  • 283 + 8626459 = 8626742
  • 499 + 8626243 = 8626742
  • 601 + 8626141 = 8626742
  • 613 + 8626129 = 8626742

Showing the first eight; more decompositions exist.
