Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489210, here are decompositions:

  • 3 + 2147489207 = 2147489210
  • 7 + 2147489203 = 2147489210
  • 67 + 2147489143 = 2147489210
  • 127 + 2147489083 = 2147489210
  • 151 + 2147489059 = 2147489210
  • 193 + 2147489017 = 2147489210
  • 631 + 2147488579 = 2147489210
  • 829 + 2147488381 = 2147489210

Showing the first eight; more decompositions exist.
