Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522416, here are decompositions:

5 + 31522411 = 31522416
43 + 31522373 = 31522416
53 + 31522363 = 31522416
59 + 31522357 = 31522416
89 + 31522327 = 31522416
103 + 31522313 = 31522416
139 + 31522277 = 31522416
173 + 31522243 = 31522416

Showing the first eight; more decompositions exist.
