Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672538, here are decompositions:

  • 11 + 8672527 = 8672538
  • 19 + 8672519 = 8672538
  • 29 + 8672509 = 8672538
  • 37 + 8672501 = 8672538
  • 67 + 8672471 = 8672538
  • 97 + 8672441 = 8672538
  • 109 + 8672429 = 8672538
  • 131 + 8672407 = 8672538

Showing the first eight; more decompositions exist.
