Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147583988, here are decompositions:

  • 5 + 2147583983 = 2147583988
  • 41 + 2147583947 = 2147583988
  • 311 + 2147583677 = 2147583988
  • 659 + 2147583329 = 2147583988
  • 839 + 2147583149 = 2147583988
  • 881 + 2147583107 = 2147583988
  • 911 + 2147583077 = 2147583988
  • 941 + 2147583047 = 2147583988

Showing the first eight; more decompositions exist.
