Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522242, here are decompositions:

13 + 31522229 = 31522242
23 + 31522219 = 31522242
61 + 31522181 = 31522242
113 + 31522129 = 31522242
139 + 31522103 = 31522242
151 + 31522091 = 31522242
181 + 31522061 = 31522242
223 + 31522019 = 31522242

Showing the first eight; more decompositions exist.
