Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496274, here are decompositions:

11 + 31496263 = 31496274
13 + 31496261 = 31496274
53 + 31496221 = 31496274
101 + 31496173 = 31496274
113 + 31496161 = 31496274
151 + 31496123 = 31496274
191 + 31496083 = 31496274
233 + 31496041 = 31496274

Showing the first eight; more decompositions exist.
