Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522826, here are decompositions:

3 + 31522823 = 31522826
79 + 31522747 = 31522826
109 + 31522717 = 31522826
157 + 31522669 = 31522826
163 + 31522663 = 31522826
193 + 31522633 = 31522826
229 + 31522597 = 31522826
277 + 31522549 = 31522826

Showing the first eight; more decompositions exist.
