Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464198, here are decompositions:

5 + 31464193 = 31464198
11 + 31464187 = 31464198
61 + 31464137 = 31464198
131 + 31464067 = 31464198
137 + 31464061 = 31464198
151 + 31464047 = 31464198
167 + 31464031 = 31464198
197 + 31464001 = 31464198

Showing the first eight; more decompositions exist.
