Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468150, here are decompositions:

3 + 31468147 = 31468150
53 + 31468097 = 31468150
83 + 31468067 = 31468150
137 + 31468013 = 31468150
149 + 31468001 = 31468150
167 + 31467983 = 31468150
239 + 31467911 = 31468150
251 + 31467899 = 31468150

Showing the first eight; more decompositions exist.
