Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479796, here are decompositions:

3 + 31479793 = 31479796
53 + 31479743 = 31479796
59 + 31479737 = 31479796
149 + 31479647 = 31479796
239 + 31479557 = 31479796
599 + 31479197 = 31479796
827 + 31478969 = 31479796
839 + 31478957 = 31479796

Showing the first eight; more decompositions exist.
