Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725198, here are decompositions:

  • 59 + 8725139 = 8725198
  • 107 + 8725091 = 8725198
  • 269 + 8724929 = 8725198
  • 479 + 8724719 = 8725198
  • 557 + 8724641 = 8725198
  • 701 + 8724497 = 8725198
  • 719 + 8724479 = 8725198
  • 761 + 8724437 = 8725198

Showing the first eight; more decompositions exist.
