Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147435700, here are decompositions:

  • 101 + 2147435599 = 2147435700
  • 131 + 2147435569 = 2147435700
  • 167 + 2147435533 = 2147435700
  • 173 + 2147435527 = 2147435700
  • 191 + 2147435509 = 2147435700
  • 199 + 2147435501 = 2147435700
  • 227 + 2147435473 = 2147435700
  • 269 + 2147435431 = 2147435700

Showing the first eight; more decompositions exist.
