Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700664, here are decompositions:

  • 83 + 8700581 = 8700664
  • 101 + 8700563 = 8700664
  • 191 + 8700473 = 8700664
  • 197 + 8700467 = 8700664
  • 233 + 8700431 = 8700664
  • 257 + 8700407 = 8700664
  • 263 + 8700401 = 8700664
  • 281 + 8700383 = 8700664

Showing the first eight; more decompositions exist.
