Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489446, here are decompositions:

5 + 2147489441 = 2147489446
23 + 2147489423 = 2147489446
149 + 2147489297 = 2147489446
239 + 2147489207 = 2147489446
359 + 2147489087 = 2147489446
449 + 2147488997 = 2147489446
587 + 2147488859 = 2147489446
653 + 2147488793 = 2147489446

Showing the first eight; more decompositions exist.
