Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683780, here are decompositions:

  • 11 + 8683769 = 8683780
  • 23 + 8683757 = 8683780
  • 89 + 8683691 = 8683780
  • 167 + 8683613 = 8683780
  • 173 + 8683607 = 8683780
  • 227 + 8683553 = 8683780
  • 239 + 8683541 = 8683780
  • 251 + 8683529 = 8683780

Showing the first eight; more decompositions exist.
