Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516054, here are decompositions:

47 + 31516007 = 31516054
113 + 31515941 = 31516054
173 + 31515881 = 31516054
197 + 31515857 = 31516054
233 + 31515821 = 31516054
443 + 31515611 = 31516054
491 + 31515563 = 31516054
641 + 31515413 = 31516054

Showing the first eight; more decompositions exist.
