Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496232, here are decompositions:

11 + 31496221 = 31496232
13 + 31496219 = 31496232
23 + 31496209 = 31496232
59 + 31496173 = 31496232
71 + 31496161 = 31496232
109 + 31496123 = 31496232
113 + 31496119 = 31496232
149 + 31496083 = 31496232

Showing the first eight; more decompositions exist.
