Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625020, here are decompositions:

  • 7 + 8625013 = 8625020
  • 13 + 8625007 = 8625020
  • 67 + 8624953 = 8625020
  • 139 + 8624881 = 8625020
  • 199 + 8624821 = 8625020
  • 307 + 8624713 = 8625020
  • 421 + 8624599 = 8625020
  • 571 + 8624449 = 8625020

Showing the first eight; more decompositions exist.
