Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507016, here are decompositions:

7 + 31507009 = 31507016
43 + 31506973 = 31507016
67 + 31506949 = 31507016
109 + 31506907 = 31507016
193 + 31506823 = 31507016
223 + 31506793 = 31507016
439 + 31506577 = 31507016
487 + 31506529 = 31507016

Showing the first eight; more decompositions exist.
