Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522908, here are decompositions:

7 + 31522901 = 31522908
19 + 31522889 = 31522908
61 + 31522847 = 31522908
191 + 31522717 = 31522908
239 + 31522669 = 31522908
251 + 31522657 = 31522908
311 + 31522597 = 31522908
317 + 31522591 = 31522908

Showing the first eight; more decompositions exist.
