Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514036, here are decompositions:

13 + 31514023 = 31514036
79 + 31513957 = 31514036
109 + 31513927 = 31514036
157 + 31513879 = 31514036
163 + 31513873 = 31514036
193 + 31513843 = 31514036
457 + 31513579 = 31514036
613 + 31513423 = 31514036

Showing the first eight; more decompositions exist.
