Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626166, here are decompositions:

113 + 31626053 = 31626166
179 + 31625987 = 31626166
197 + 31625969 = 31626166
227 + 31625939 = 31626166
317 + 31625849 = 31626166
347 + 31625819 = 31626166
359 + 31625807 = 31626166
389 + 31625777 = 31626166

Showing the first eight; more decompositions exist.
