Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621052, here are decompositions:

19 + 31621033 = 31621052
79 + 31620973 = 31621052
109 + 31620943 = 31621052
181 + 31620871 = 31621052
373 + 31620679 = 31621052
571 + 31620481 = 31621052
643 + 31620409 = 31621052
709 + 31620343 = 31621052

Showing the first eight; more decompositions exist.
