Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514146, here are decompositions:

3 + 31514143 = 31514146
179 + 31513967 = 31514146
269 + 31513877 = 31514146
353 + 31513793 = 31514146
359 + 31513787 = 31514146
449 + 31513697 = 31514146
479 + 31513667 = 31514146
743 + 31513403 = 31514146

Showing the first eight; more decompositions exist.
