Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559814, here are decompositions:

5 + 31559809 = 31559814
31 + 31559783 = 31559814
37 + 31559777 = 31559814
43 + 31559771 = 31559814
127 + 31559687 = 31559814
137 + 31559677 = 31559814
163 + 31559651 = 31559814
173 + 31559641 = 31559814

Showing the first eight; more decompositions exist.
