Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514506, here are decompositions:

29 + 31514477 = 31514506
83 + 31514423 = 31514506
197 + 31514309 = 31514506
239 + 31514267 = 31514506
347 + 31514159 = 31514506
563 + 31513943 = 31514506
719 + 31513787 = 31514506
797 + 31513709 = 31514506

Showing the first eight; more decompositions exist.
