Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643370, here are decompositions:

  • 3 + 8643367 = 8643370
  • 11 + 8643359 = 8643370
  • 53 + 8643317 = 8643370
  • 83 + 8643287 = 8643370
  • 89 + 8643281 = 8643370
  • 173 + 8643197 = 8643370
  • 227 + 8643143 = 8643370
  • 233 + 8643137 = 8643370

Showing the first eight; more decompositions exist.
