Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514500, here are decompositions:

23 + 31514477 = 31514500
71 + 31514429 = 31514500
191 + 31514309 = 31514500
233 + 31514267 = 31514500
239 + 31514261 = 31514500
419 + 31514081 = 31514500
557 + 31513943 = 31514500
683 + 31513817 = 31514500

Showing the first eight; more decompositions exist.
