Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488844, here are decompositions:

103 + 2147488741 = 2147488844
271 + 2147488573 = 2147488844
433 + 2147488411 = 2147488844
463 + 2147488381 = 2147488844
673 + 2147488171 = 2147488844
691 + 2147488153 = 2147488844
733 + 2147488111 = 2147488844
937 + 2147487907 = 2147488844

Showing the first eight; more decompositions exist.
