Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464180, here are decompositions:

31 + 31464149 = 31464180
37 + 31464143 = 31464180
43 + 31464137 = 31464180
101 + 31464079 = 31464180
113 + 31464067 = 31464180
149 + 31464031 = 31464180
179 + 31464001 = 31464180
239 + 31463941 = 31464180

Showing the first eight; more decompositions exist.
