Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672438, here are decompositions:

  • 31 + 8672407 = 8672438
  • 199 + 8672239 = 8672438
  • 277 + 8672161 = 8672438
  • 337 + 8672101 = 8672438
  • 457 + 8671981 = 8672438
  • 601 + 8671837 = 8672438
  • 727 + 8671711 = 8672438
  • 769 + 8671669 = 8672438

Showing the first eight; more decompositions exist.
