Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624106, here are decompositions:

37 + 31624069 = 31624106
103 + 31624003 = 31624106
127 + 31623979 = 31624106
139 + 31623967 = 31624106
439 + 31623667 = 31624106
499 + 31623607 = 31624106
607 + 31623499 = 31624106
733 + 31623373 = 31624106

Showing the first eight; more decompositions exist.
