Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522496, here are decompositions:

3 + 31522493 = 31522496
37 + 31522459 = 31522496
139 + 31522357 = 31522496
157 + 31522339 = 31522496
199 + 31522297 = 31522496
277 + 31522219 = 31522496
367 + 31522129 = 31522496
613 + 31521883 = 31522496

Showing the first eight; more decompositions exist.
