Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522616, here are decompositions:

3 + 31522613 = 31522616
19 + 31522597 = 31522616
67 + 31522549 = 31522616
157 + 31522459 = 31522616
277 + 31522339 = 31522616
373 + 31522243 = 31522616
397 + 31522219 = 31522616
409 + 31522207 = 31522616

Showing the first eight; more decompositions exist.
