Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503914, here are decompositions:

3 + 31503911 = 31503914
31 + 31503883 = 31503914
61 + 31503853 = 31503914
67 + 31503847 = 31503914
73 + 31503841 = 31503914
103 + 31503811 = 31503914
163 + 31503751 = 31503914
181 + 31503733 = 31503914

Showing the first eight; more decompositions exist.
