Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540014, here are decompositions:

5 + 31540009 = 31540014
7 + 31540007 = 31540014
43 + 31539971 = 31540014
47 + 31539967 = 31540014
83 + 31539931 = 31540014
113 + 31539901 = 31540014
151 + 31539863 = 31540014
157 + 31539857 = 31540014

Showing the first eight; more decompositions exist.
