Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702786, here are decompositions:

  • 97 + 8702689 = 8702786
  • 139 + 8702647 = 8702786
  • 193 + 8702593 = 8702786
  • 199 + 8702587 = 8702786
  • 229 + 8702557 = 8702786
  • 283 + 8702503 = 8702786
  • 457 + 8702329 = 8702786
  • 607 + 8702179 = 8702786

Showing the first eight; more decompositions exist.
