Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540134, here are decompositions:

11 + 31540123 = 31540134
71 + 31540063 = 31540134
103 + 31540031 = 31540134
127 + 31540007 = 31540134
163 + 31539971 = 31540134
167 + 31539967 = 31540134
233 + 31539901 = 31540134
271 + 31539863 = 31540134

Showing the first eight; more decompositions exist.
