Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514038, here are decompositions:

71 + 31513967 = 31514038
251 + 31513787 = 31514038
317 + 31513721 = 31514038
431 + 31513607 = 31514038
947 + 31513091 = 31514038
1031 + 31513007 = 31514038
1091 + 31512947 = 31514038
1259 + 31512779 = 31514038

Showing the first eight; more decompositions exist.
