Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624118, here are decompositions:

139 + 31623979 = 31624118
151 + 31623967 = 31624118
397 + 31623721 = 31624118
607 + 31623511 = 31624118
619 + 31623499 = 31624118
907 + 31623211 = 31624118
919 + 31623199 = 31624118
937 + 31623181 = 31624118

Showing the first eight; more decompositions exist.
