Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621496, here are decompositions:

19 + 31621477 = 31621496
79 + 31621417 = 31621496
97 + 31621399 = 31621496
103 + 31621393 = 31621496
139 + 31621357 = 31621496
229 + 31621267 = 31621496
373 + 31621123 = 31621496
433 + 31621063 = 31621496

Showing the first eight; more decompositions exist.
