Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147456976, here are decompositions:

  • 13 + 2147456963 = 2147456976
  • 19 + 2147456957 = 2147456976
  • 47 + 2147456929 = 2147456976
  • 53 + 2147456923 = 2147456976
  • 73 + 2147456903 = 2147456976
  • 89 + 2147456887 = 2147456976
  • 97 + 2147456879 = 2147456976
  • 107 + 2147456869 = 2147456976

Showing the first eight; more decompositions exist.
