Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500778, here are decompositions:

151 + 2147500627 = 2147500778
271 + 2147500507 = 2147500778
439 + 2147500339 = 2147500778
601 + 2147500177 = 2147500778
937 + 2147499841 = 2147500778
1051 + 2147499727 = 2147500778
1201 + 2147499577 = 2147500778
1231 + 2147499547 = 2147500778

Showing the first eight; more decompositions exist.
