Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624146, here are decompositions:

5 + 31624141 = 31624146
17 + 31624129 = 31624146
19 + 31624127 = 31624146
157 + 31623989 = 31624146
163 + 31623983 = 31624146
167 + 31623979 = 31624146
179 + 31623967 = 31624146
193 + 31623953 = 31624146

Showing the first eight; more decompositions exist.
