Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489970, here are decompositions:

  • 13 + 2147489957 = 2147489970
  • 23 + 2147489947 = 2147489970
  • 29 + 2147489941 = 2147489970
  • 53 + 2147489917 = 2147489970
  • 61 + 2147489909 = 2147489970
  • 71 + 2147489899 = 2147489970
  • 97 + 2147489873 = 2147489970
  • 127 + 2147489843 = 2147489970

Showing the first eight; more decompositions exist.
