Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514292, here are decompositions:

31 + 31514261 = 31514292
53 + 31514239 = 31514292
71 + 31514221 = 31514292
101 + 31514191 = 31514292
149 + 31514143 = 31514292
179 + 31514113 = 31514292
191 + 31514101 = 31514292
211 + 31514081 = 31514292

Showing the first eight; more decompositions exist.
