Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472748, here are decompositions:

59 + 2147472689 = 2147472748
89 + 2147472659 = 2147472748
131 + 2147472617 = 2147472748
137 + 2147472611 = 2147472748
191 + 2147472557 = 2147472748
257 + 2147472491 = 2147472748
587 + 2147472161 = 2147472748
647 + 2147472101 = 2147472748

Showing the first eight; more decompositions exist.
