Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625680, here are decompositions:

  • 31 + 8625649 = 8625680
  • 43 + 8625637 = 8625680
  • 127 + 8625553 = 8625680
  • 139 + 8625541 = 8625680
  • 163 + 8625517 = 8625680
  • 229 + 8625451 = 8625680
  • 331 + 8625349 = 8625680
  • 337 + 8625343 = 8625680

Showing the first eight; more decompositions exist.
