Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681260, here are decompositions:

  • 17 + 8681243 = 8681260
  • 47 + 8681213 = 8681260
  • 53 + 8681207 = 8681260
  • 83 + 8681177 = 8681260
  • 101 + 8681159 = 8681260
  • 131 + 8681129 = 8681260
  • 149 + 8681111 = 8681260
  • 239 + 8681021 = 8681260

Showing the first eight; more decompositions exist.
