Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626174, here are decompositions:

7 + 31626167 = 31626174
43 + 31626131 = 31626174
101 + 31626073 = 31626174
163 + 31626011 = 31626174
193 + 31625981 = 31626174
211 + 31625963 = 31626174
257 + 31625917 = 31626174
263 + 31625911 = 31626174

Showing the first eight; more decompositions exist.
