Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147454632, here are decompositions:

  • 3 + 2147454629 = 2147454632
  • 109 + 2147454523 = 2147454632
  • 139 + 2147454493 = 2147454632
  • 151 + 2147454481 = 2147454632
  • 229 + 2147454403 = 2147454632
  • 241 + 2147454391 = 2147454632
  • 613 + 2147454019 = 2147454632
  • 751 + 2147453881 = 2147454632

Showing the first eight; more decompositions exist.
