Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626154, here are decompositions:

23 + 31626131 = 31626154
101 + 31626053 = 31626154
113 + 31626041 = 31626154
167 + 31625987 = 31626154
173 + 31625981 = 31626154
191 + 31625963 = 31626154
311 + 31625843 = 31626154
347 + 31625807 = 31626154

Showing the first eight; more decompositions exist.
