Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489972, here are decompositions:

3 + 2147489969 = 2147489972
31 + 2147489941 = 2147489972
73 + 2147489899 = 2147489972
151 + 2147489821 = 2147489972
499 + 2147489473 = 2147489972
571 + 2147489401 = 2147489972
673 + 2147489299 = 2147489972
709 + 2147489263 = 2147489972

Showing the first eight; more decompositions exist.
