Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522398, here are decompositions:

41 + 31522357 = 31522398
59 + 31522339 = 31522398
67 + 31522331 = 31522398
71 + 31522327 = 31522398
101 + 31522297 = 31522398
151 + 31522247 = 31522398
157 + 31522241 = 31522398
179 + 31522219 = 31522398

Showing the first eight; more decompositions exist.
