Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508796, here are decompositions:

5 + 31508791 = 31508796
83 + 31508713 = 31508796
113 + 31508683 = 31508796
139 + 31508657 = 31508796
149 + 31508647 = 31508796
157 + 31508639 = 31508796
227 + 31508569 = 31508796
229 + 31508567 = 31508796

Showing the first eight; more decompositions exist.
