Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491974, here are decompositions:

  • 13 + 2147491961 = 2147491974
  • 37 + 2147491937 = 2147491974
  • 71 + 2147491903 = 2147491974
  • 137 + 2147491837 = 2147491974
  • 193 + 2147491781 = 2147491974
  • 241 + 2147491733 = 2147491974
  • 283 + 2147491691 = 2147491974
  • 367 + 2147491607 = 2147491974

Showing the first eight; more decompositions exist.
