Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489728, here are decompositions:

  • 11 + 2147489717 = 2147489728
  • 29 + 2147489699 = 2147489728
  • 89 + 2147489639 = 2147489728
  • 149 + 2147489579 = 2147489728
  • 191 + 2147489537 = 2147489728
  • 431 + 2147489297 = 2147489728
  • 521 + 2147489207 = 2147489728
  • 641 + 2147489087 = 2147489728

Showing the first eight; more decompositions exist.
