Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624082, here are decompositions:

13 + 31624069 = 31624082
79 + 31624003 = 31624082
103 + 31623979 = 31624082
151 + 31623931 = 31624082
181 + 31623901 = 31624082
379 + 31623703 = 31624082
571 + 31623511 = 31624082
601 + 31623481 = 31624082

Showing the first eight; more decompositions exist.
