Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464072, here are decompositions:

5 + 31464067 = 31464072
11 + 31464061 = 31464072
41 + 31464031 = 31464072
71 + 31464001 = 31464072
109 + 31463963 = 31464072
113 + 31463959 = 31464072
131 + 31463941 = 31464072
151 + 31463921 = 31464072

Showing the first eight; more decompositions exist.
