Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522254, here are decompositions:

7 + 31522247 = 31522254
11 + 31522243 = 31522254
13 + 31522241 = 31522254
47 + 31522207 = 31522254
73 + 31522181 = 31522254
151 + 31522103 = 31522254
163 + 31522091 = 31522254
193 + 31522061 = 31522254

Showing the first eight; more decompositions exist.
