Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548174, here are decompositions:

41 + 31548133 = 31548174
71 + 31548103 = 31548174
127 + 31548047 = 31548174
157 + 31548017 = 31548174
167 + 31548007 = 31548174
181 + 31547993 = 31548174
193 + 31547981 = 31548174
241 + 31547933 = 31548174

Showing the first eight; more decompositions exist.
