Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467180, here are decompositions:

11 + 31467169 = 31467180
13 + 31467167 = 31467180
23 + 31467157 = 31467180
47 + 31467133 = 31467180
53 + 31467127 = 31467180
97 + 31467083 = 31467180
109 + 31467071 = 31467180
113 + 31467067 = 31467180

Showing the first eight; more decompositions exist.
