Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147568982, here are decompositions:

  • 5 + 2147568977 = 2147568982
  • 29 + 2147568953 = 2147568982
  • 101 + 2147568881 = 2147568982
  • 113 + 2147568869 = 2147568982
  • 149 + 2147568833 = 2147568982
  • 233 + 2147568749 = 2147568982
  • 281 + 2147568701 = 2147568982
  • 353 + 2147568629 = 2147568982

Showing the first eight; more decompositions exist.
