Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404442, here are decompositions:

  • 3 + 2147404439 = 2147404442
  • 13 + 2147404429 = 2147404442
  • 61 + 2147404381 = 2147404442
  • 199 + 2147404243 = 2147404442
  • 661 + 2147403781 = 2147404442
  • 769 + 2147403673 = 2147404442
  • 1033 + 2147403409 = 2147404442
  • 1039 + 2147403403 = 2147404442

Showing the first eight; more decompositions exist.
