Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624158, here are decompositions:

11 + 31624147 = 31624158
17 + 31624141 = 31624158
29 + 31624129 = 31624158
31 + 31624127 = 31624158
89 + 31624069 = 31624158
157 + 31624001 = 31624158
179 + 31623979 = 31624158
191 + 31623967 = 31624158

Showing the first eight; more decompositions exist.
