Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446108, here are decompositions:

7 + 31446101 = 31446108
11 + 31446097 = 31446108
41 + 31446067 = 31446108
47 + 31446061 = 31446108
97 + 31446011 = 31446108
131 + 31445977 = 31446108
149 + 31445959 = 31446108
151 + 31445957 = 31446108

Showing the first eight; more decompositions exist.
