Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514272, here are decompositions:

5 + 31514267 = 31514272
11 + 31514261 = 31514272
113 + 31514159 = 31514272
191 + 31514081 = 31514272
479 + 31513793 = 31514272
563 + 31513709 = 31514272
659 + 31513613 = 31514272
941 + 31513331 = 31514272

Showing the first eight; more decompositions exist.
