Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443674, here are decompositions:

  • 41 + 2147443633 = 2147443674
  • 71 + 2147443603 = 2147443674
  • 107 + 2147443567 = 2147443674
  • 113 + 2147443561 = 2147443674
  • 127 + 2147443547 = 2147443674
  • 137 + 2147443537 = 2147443674
  • 151 + 2147443523 = 2147443674
  • 251 + 2147443423 = 2147443674

Showing the first eight; more decompositions exist.
