Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479654, here are decompositions:

5 + 31479649 = 31479654
7 + 31479647 = 31479654
61 + 31479593 = 31479654
97 + 31479557 = 31479654
103 + 31479551 = 31479654
113 + 31479541 = 31479654
137 + 31479517 = 31479654
163 + 31479491 = 31479654

Showing the first eight; more decompositions exist.
