Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622494, here are decompositions:

3 + 31622491 = 31622494
257 + 31622237 = 31622494
311 + 31622183 = 31622494
347 + 31622147 = 31622494
353 + 31622141 = 31622494
593 + 31621901 = 31622494
647 + 31621847 = 31622494
821 + 31621673 = 31622494

Showing the first eight; more decompositions exist.
