Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672490, here are decompositions:

  • 7 + 8672483 = 8672490
  • 19 + 8672471 = 8672490
  • 61 + 8672429 = 8672490
  • 67 + 8672423 = 8672490
  • 83 + 8672407 = 8672490
  • 103 + 8672387 = 8672490
  • 109 + 8672381 = 8672490
  • 137 + 8672353 = 8672490

Showing the first eight; more decompositions exist.
