Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522282, here are decompositions:

5 + 31522277 = 31522282
41 + 31522241 = 31522282
53 + 31522229 = 31522282
101 + 31522181 = 31522282
179 + 31522103 = 31522282
191 + 31522091 = 31522282
263 + 31522019 = 31522282
269 + 31522013 = 31522282

Showing the first eight; more decompositions exist.
