Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522290, here are decompositions:

13 + 31522277 = 31522290
43 + 31522247 = 31522290
47 + 31522243 = 31522290
61 + 31522229 = 31522290
71 + 31522219 = 31522290
83 + 31522207 = 31522290
109 + 31522181 = 31522290
199 + 31522091 = 31522290

Showing the first eight; more decompositions exist.
