Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479774, here are decompositions:

5 + 31479769 = 31479774
17 + 31479757 = 31479774
31 + 31479743 = 31479774
37 + 31479737 = 31479774
103 + 31479671 = 31479774
127 + 31479647 = 31479774
181 + 31479593 = 31479774
197 + 31479577 = 31479774

Showing the first eight; more decompositions exist.
