Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621934, here are decompositions:

37 + 31621897 = 31621934
103 + 31621831 = 31621934
181 + 31621753 = 31621934
241 + 31621693 = 31621934
283 + 31621651 = 31621934
313 + 31621621 = 31621934
373 + 31621561 = 31621934
433 + 31621501 = 31621934

Showing the first eight; more decompositions exist.
