Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626168, here are decompositions:

37 + 31626131 = 31626168
59 + 31626109 = 31626168
89 + 31626079 = 31626168
127 + 31626041 = 31626168
149 + 31626019 = 31626168
157 + 31626011 = 31626168
181 + 31625987 = 31626168
199 + 31625969 = 31626168

Showing the first eight; more decompositions exist.
