Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664646, here are decompositions:

  • 173 + 8664473 = 8664646
  • 227 + 8664419 = 8664646
  • 233 + 8664413 = 8664646
  • 257 + 8664389 = 8664646
  • 269 + 8664377 = 8664646
  • 317 + 8664329 = 8664646
  • 593 + 8664053 = 8664646
  • 659 + 8663987 = 8664646

Showing the first eight; more decompositions exist.
