Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464150, here are decompositions:

7 + 31464143 = 31464150
13 + 31464137 = 31464150
71 + 31464079 = 31464150
83 + 31464067 = 31464150
89 + 31464061 = 31464150
103 + 31464047 = 31464150
149 + 31464001 = 31464150
191 + 31463959 = 31464150

Showing the first eight; more decompositions exist.
