Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496292, here are decompositions:

29 + 31496263 = 31496292
31 + 31496261 = 31496292
71 + 31496221 = 31496292
73 + 31496219 = 31496292
83 + 31496209 = 31496292
131 + 31496161 = 31496292
151 + 31496141 = 31496292
173 + 31496119 = 31496292

Showing the first eight; more decompositions exist.
