Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620596, here are decompositions:

19 + 31620577 = 31620596
79 + 31620517 = 31620596
97 + 31620499 = 31620596
109 + 31620487 = 31620596
199 + 31620397 = 31620596
367 + 31620229 = 31620596
373 + 31620223 = 31620596
457 + 31620139 = 31620596

Showing the first eight; more decompositions exist.
