Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522316, here are decompositions:

3 + 31522313 = 31522316
19 + 31522297 = 31522316
73 + 31522243 = 31522316
97 + 31522219 = 31522316
109 + 31522207 = 31522316
337 + 31521979 = 31522316
433 + 31521883 = 31522316
487 + 31521829 = 31522316

Showing the first eight; more decompositions exist.
