Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489428, here are decompositions:

  • 5 + 2147489423 = 2147489428
  • 131 + 2147489297 = 2147489428
  • 137 + 2147489291 = 2147489428
  • 431 + 2147488997 = 2147489428
  • 509 + 2147488919 = 2147489428
  • 521 + 2147488907 = 2147489428
  • 569 + 2147488859 = 2147489428
  • 677 + 2147488751 = 2147489428

Showing the first eight; more decompositions exist.
