Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443602, here are decompositions:

  • 13 + 2147443589 = 2147443602
  • 23 + 2147443579 = 2147443602
  • 41 + 2147443561 = 2147443602
  • 79 + 2147443523 = 2147443602
  • 89 + 2147443513 = 2147443602
  • 131 + 2147443471 = 2147443602
  • 179 + 2147443423 = 2147443602
  • 181 + 2147443421 = 2147443602

Showing the first eight; more decompositions exist.
