Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670688, here are decompositions:

  • 137 + 8670551 = 8670688
  • 179 + 8670509 = 8670688
  • 197 + 8670491 = 8670688
  • 281 + 8670407 = 8670688
  • 317 + 8670371 = 8670688
  • 431 + 8670257 = 8670688
  • 449 + 8670239 = 8670688
  • 491 + 8670197 = 8670688

Showing the first eight; more decompositions exist.
