Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500878, here are decompositions:

  • 7 + 2147500871 = 2147500878
  • 97 + 2147500781 = 2147500878
  • 181 + 2147500697 = 2147500878
  • 251 + 2147500627 = 2147500878
  • 317 + 2147500561 = 2147500878
  • 379 + 2147500499 = 2147500878
  • 577 + 2147500301 = 2147500878
  • 619 + 2147500259 = 2147500878

Showing the first eight; more decompositions exist.
