Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626192, here are decompositions:

61 + 31626131 = 31626192
83 + 31626109 = 31626192
113 + 31626079 = 31626192
139 + 31626053 = 31626192
151 + 31626041 = 31626192
173 + 31626019 = 31626192
181 + 31626011 = 31626192
211 + 31625981 = 31626192

Showing the first eight; more decompositions exist.
