Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702660, here are decompositions:

  • 13 + 8702647 = 8702660
  • 67 + 8702593 = 8702660
  • 73 + 8702587 = 8702660
  • 103 + 8702557 = 8702660
  • 157 + 8702503 = 8702660
  • 163 + 8702497 = 8702660
  • 229 + 8702431 = 8702660
  • 331 + 8702329 = 8702660

Showing the first eight; more decompositions exist.
