Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672620, here are decompositions:

  • 23 + 8672597 = 8672620
  • 59 + 8672561 = 8672620
  • 101 + 8672519 = 8672620
  • 107 + 8672513 = 8672620
  • 137 + 8672483 = 8672620
  • 149 + 8672471 = 8672620
  • 179 + 8672441 = 8672620
  • 191 + 8672429 = 8672620

Showing the first eight; more decompositions exist.
