Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481660, here are decompositions:

  • 31 + 2147481629 = 2147481660
  • 89 + 2147481571 = 2147481660
  • 97 + 2147481563 = 2147481660
  • 131 + 2147481529 = 2147481660
  • 151 + 2147481509 = 2147481660
  • 173 + 2147481487 = 2147481660
  • 293 + 2147481367 = 2147481660
  • 307 + 2147481353 = 2147481660

Showing the first eight; more decompositions exist.
