Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480988, here are decompositions:

  • 17 + 2147480971 = 2147480988
  • 19 + 2147480969 = 2147480988
  • 31 + 2147480957 = 2147480988
  • 47 + 2147480941 = 2147480988
  • 61 + 2147480927 = 2147480988
  • 67 + 2147480921 = 2147480988
  • 89 + 2147480899 = 2147480988
  • 139 + 2147480849 = 2147480988

Showing the first eight; more decompositions exist.
