Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672818, here are decompositions:

  • 17 + 8672801 = 8672818
  • 29 + 8672789 = 8672818
  • 131 + 8672687 = 8672818
  • 179 + 8672639 = 8672818
  • 197 + 8672621 = 8672818
  • 257 + 8672561 = 8672818
  • 317 + 8672501 = 8672818
  • 347 + 8672471 = 8672818

Showing the first eight; more decompositions exist.
