Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147479884, here are decompositions:

  • 5 + 2147479879 = 2147479884
  • 61 + 2147479823 = 2147479884
  • 97 + 2147479787 = 2147479884
  • 103 + 2147479781 = 2147479884
  • 127 + 2147479757 = 2147479884
  • 131 + 2147479753 = 2147479884
  • 227 + 2147479657 = 2147479884
  • 241 + 2147479643 = 2147479884

Showing the first eight; more decompositions exist.
