Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479714, here are decompositions:

17 + 31479697 = 31479714
43 + 31479671 = 31479714
67 + 31479647 = 31479714
137 + 31479577 = 31479714
157 + 31479557 = 31479714
163 + 31479551 = 31479714
173 + 31479541 = 31479714
197 + 31479517 = 31479714

Showing the first eight; more decompositions exist.
