Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479980, here are decompositions:

  • 43 + 2147479937 = 2147479980
  • 73 + 2147479907 = 2147479980
  • 83 + 2147479897 = 2147479980
  • 89 + 2147479891 = 2147479980
  • 101 + 2147479879 = 2147479980
  • 157 + 2147479823 = 2147479980
  • 193 + 2147479787 = 2147479980
  • 199 + 2147479781 = 2147479980

Showing the first eight; more decompositions exist.
