Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514040, here are decompositions:

17 + 31514023 = 31514040
53 + 31513987 = 31514040
73 + 31513967 = 31514040
83 + 31513957 = 31514040
97 + 31513943 = 31514040
113 + 31513927 = 31514040
149 + 31513891 = 31514040
163 + 31513877 = 31514040

Showing the first eight; more decompositions exist.
