Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468974, here are decompositions:

  • 3 + 2147468971 = 2147468974
  • 41 + 2147468933 = 2147468974
  • 113 + 2147468861 = 2147468974
  • 173 + 2147468801 = 2147468974
  • 191 + 2147468783 = 2147468974
  • 257 + 2147468717 = 2147468974
  • 353 + 2147468621 = 2147468974
  • 383 + 2147468591 = 2147468974

Showing the first eight; more decompositions exist.
