Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522466, here are decompositions:

7 + 31522459 = 31522466
103 + 31522363 = 31522466
109 + 31522357 = 31522466
127 + 31522339 = 31522466
139 + 31522327 = 31522466
223 + 31522243 = 31522466
337 + 31522129 = 31522466
487 + 31521979 = 31522466

Showing the first eight; more decompositions exist.
