Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537422, here are decompositions:

13 + 31537409 = 31537422
31 + 31537391 = 31537422
83 + 31537339 = 31537422
109 + 31537313 = 31537422
113 + 31537309 = 31537422
149 + 31537273 = 31537422
151 + 31537271 = 31537422
179 + 31537243 = 31537422

Showing the first eight; more decompositions exist.
