Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489880, here are decompositions:

  • 7 + 2147489873 = 2147489880
  • 31 + 2147489849 = 2147489880
  • 37 + 2147489843 = 2147489880
  • 59 + 2147489821 = 2147489880
  • 61 + 2147489819 = 2147489880
  • 83 + 2147489797 = 2147489880
  • 163 + 2147489717 = 2147489880
  • 167 + 2147489713 = 2147489880

Showing the first eight; more decompositions exist.
