Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522344, here are decompositions:

5 + 31522339 = 31522344
13 + 31522331 = 31522344
17 + 31522327 = 31522344
31 + 31522313 = 31522344
47 + 31522297 = 31522344
67 + 31522277 = 31522344
97 + 31522247 = 31522344
101 + 31522243 = 31522344

Showing the first eight; more decompositions exist.
