Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479694, here are decompositions:

23 + 31479671 = 31479694
47 + 31479647 = 31479694
101 + 31479593 = 31479694
137 + 31479557 = 31479694
227 + 31479467 = 31479694
443 + 31479251 = 31479694
563 + 31479131 = 31479694
593 + 31479101 = 31479694

Showing the first eight; more decompositions exist.
