Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479612, here are decompositions:

19 + 31479593 = 31479612
23 + 31479589 = 31479612
53 + 31479559 = 31479612
61 + 31479551 = 31479612
71 + 31479541 = 31479612
113 + 31479499 = 31479612
173 + 31479439 = 31479612
191 + 31479421 = 31479612

Showing the first eight; more decompositions exist.
