Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516014, here are decompositions:

7 + 31516007 = 31516014
73 + 31515941 = 31516014
83 + 31515931 = 31516014
157 + 31515857 = 31516014
193 + 31515821 = 31516014
251 + 31515763 = 31516014
281 + 31515733 = 31516014
311 + 31515703 = 31516014

Showing the first eight; more decompositions exist.
