Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493044, here are decompositions:

7 + 2147493037 = 2147493044
43 + 2147493001 = 2147493044
373 + 2147492671 = 2147493044
523 + 2147492521 = 2147493044
673 + 2147492371 = 2147493044
691 + 2147492353 = 2147493044
727 + 2147492317 = 2147493044
883 + 2147492161 = 2147493044

Showing the first eight; more decompositions exist.
