Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534266, here are decompositions:

19 + 31534247 = 31534266
67 + 31534199 = 31534266
79 + 31534187 = 31534266
83 + 31534183 = 31534266
97 + 31534169 = 31534266
149 + 31534117 = 31534266
163 + 31534103 = 31534266
193 + 31534073 = 31534266

Showing the first eight; more decompositions exist.
