Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467108, here are decompositions:

5 + 31467103 = 31467108
19 + 31467089 = 31467108
37 + 31467071 = 31467108
41 + 31467067 = 31467108
97 + 31467011 = 31467108
109 + 31466999 = 31467108
131 + 31466977 = 31467108
139 + 31466969 = 31467108

Showing the first eight; more decompositions exist.
