Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508214, here are decompositions:

11 + 31508203 = 31508214
37 + 31508177 = 31508214
43 + 31508171 = 31508214
61 + 31508153 = 31508214
71 + 31508143 = 31508214
107 + 31508107 = 31508214
113 + 31508101 = 31508214
131 + 31508083 = 31508214

Showing the first eight; more decompositions exist.
