Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472790, here are decompositions:

3 + 2147472787 = 2147472790
101 + 2147472689 = 2147472790
107 + 2147472683 = 2147472790
131 + 2147472659 = 2147472790
173 + 2147472617 = 2147472790
179 + 2147472611 = 2147472790
233 + 2147472557 = 2147472790
347 + 2147472443 = 2147472790

Showing the first eight; more decompositions exist.
