Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147504278, here are decompositions:

  • 11 + 2147504267 = 2147504278
  • 89 + 2147504189 = 2147504278
  • 107 + 2147504171 = 2147504278
  • 461 + 2147503817 = 2147504278
  • 827 + 2147503451 = 2147504278
  • 839 + 2147503439 = 2147504278
  • 929 + 2147503349 = 2147504278
  • 977 + 2147503301 = 2147504278

Showing the first eight; more decompositions exist.
