Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577116, here are decompositions:

3 + 31577113 = 31577116
59 + 31577057 = 31577116
107 + 31577009 = 31577116
149 + 31576967 = 31577116
167 + 31576949 = 31577116
227 + 31576889 = 31577116
443 + 31576673 = 31577116
587 + 31576529 = 31577116

Showing the first eight; more decompositions exist.
