Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489374, here are decompositions:

83 + 2147489291 = 2147489374
131 + 2147489243 = 2147489374
167 + 2147489207 = 2147489374
461 + 2147488913 = 2147489374
467 + 2147488907 = 2147489374
647 + 2147488727 = 2147489374
683 + 2147488691 = 2147489374
761 + 2147488613 = 2147489374

Showing the first eight; more decompositions exist.
