Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624166, here are decompositions:

19 + 31624147 = 31624166
37 + 31624129 = 31624166
97 + 31624069 = 31624166
163 + 31624003 = 31624166
199 + 31623967 = 31624166
349 + 31623817 = 31624166
463 + 31623703 = 31624166
499 + 31623667 = 31624166

Showing the first eight; more decompositions exist.
