Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522338, here are decompositions:

7 + 31522331 = 31522338
11 + 31522327 = 31522338
41 + 31522297 = 31522338
61 + 31522277 = 31522338
97 + 31522241 = 31522338
109 + 31522229 = 31522338
131 + 31522207 = 31522338
157 + 31522181 = 31522338

Showing the first eight; more decompositions exist.
