Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493658, here are decompositions:

29 + 2147493629 = 2147493658
41 + 2147493617 = 2147493658
59 + 2147493599 = 2147493658
179 + 2147493479 = 2147493658
347 + 2147493311 = 2147493658
641 + 2147493017 = 2147493658
719 + 2147492939 = 2147493658
1019 + 2147492639 = 2147493658

Showing the first eight; more decompositions exist.
