Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500978, here are decompositions:

  • 41 + 2147500937 = 2147500978
  • 47 + 2147500931 = 2147500978
  • 71 + 2147500907 = 2147500978
  • 89 + 2147500889 = 2147500978
  • 107 + 2147500871 = 2147500978
  • 197 + 2147500781 = 2147500978
  • 281 + 2147500697 = 2147500978
  • 317 + 2147500661 = 2147500978

Showing the first eight; more decompositions exist.
