Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514066, here are decompositions:

7 + 31514059 = 31514066
43 + 31514023 = 31514066
79 + 31513987 = 31514066
109 + 31513957 = 31514066
139 + 31513927 = 31514066
193 + 31513873 = 31514066
223 + 31513843 = 31514066
373 + 31513693 = 31514066

Showing the first eight; more decompositions exist.
