Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626306, here are decompositions:

59 + 31626247 = 31626306
73 + 31626233 = 31626306
97 + 31626209 = 31626306
109 + 31626197 = 31626306
113 + 31626193 = 31626306
139 + 31626167 = 31626306
197 + 31626109 = 31626306
227 + 31626079 = 31626306

Showing the first eight; more decompositions exist.
