Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638826, here are decompositions:

  • 19 + 8638807 = 8638826
  • 139 + 8638687 = 8638826
  • 193 + 8638633 = 8638826
  • 199 + 8638627 = 8638826
  • 283 + 8638543 = 8638826
  • 349 + 8638477 = 8638826
  • 373 + 8638453 = 8638826
  • 379 + 8638447 = 8638826

Showing the first eight; more decompositions exist.
