Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488862, here are decompositions:

3 + 2147488859 = 2147488862
283 + 2147488579 = 2147488862
433 + 2147488429 = 2147488862
613 + 2147488249 = 2147488862
691 + 2147488171 = 2147488862
709 + 2147488153 = 2147488862
751 + 2147488111 = 2147488862
853 + 2147488009 = 2147488862

Showing the first eight; more decompositions exist.
