Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519714, here are decompositions:

3 + 31519711 = 31519714
11 + 31519703 = 31519714
41 + 31519673 = 31519714
53 + 31519661 = 31519714
113 + 31519601 = 31519714
131 + 31519583 = 31519714
227 + 31519487 = 31519714
251 + 31519463 = 31519714

Showing the first eight; more decompositions exist.
