Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503894, here are decompositions:

7 + 31503887 = 31503894
11 + 31503883 = 31503894
31 + 31503863 = 31503894
41 + 31503853 = 31503894
47 + 31503847 = 31503894
53 + 31503841 = 31503894
83 + 31503811 = 31503894
167 + 31503727 = 31503894

Showing the first eight; more decompositions exist.
