Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491118, here are decompositions:

7 + 2147491111 = 2147491118
37 + 2147491081 = 2147491118
151 + 2147490967 = 2147491118
307 + 2147490811 = 2147491118
349 + 2147490769 = 2147491118
379 + 2147490739 = 2147491118
541 + 2147490577 = 2147491118
631 + 2147490487 = 2147491118

Showing the first eight; more decompositions exist.
