Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489194, here are decompositions:

  • 107 + 2147489087 = 2147489194
  • 197 + 2147488997 = 2147489194
  • 281 + 2147488913 = 2147489194
  • 401 + 2147488793 = 2147489194
  • 443 + 2147488751 = 2147489194
  • 467 + 2147488727 = 2147489194
  • 503 + 2147488691 = 2147489194
  • 677 + 2147488517 = 2147489194

Showing the first eight; more decompositions exist.
