Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457106, here are decompositions:

7 + 31457099 = 31457106
13 + 31457093 = 31457106
67 + 31457039 = 31457106
97 + 31457009 = 31457106
157 + 31456949 = 31457106
179 + 31456927 = 31457106
223 + 31456883 = 31457106
257 + 31456849 = 31457106

Showing the first eight; more decompositions exist.
