Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467186, here are decompositions:

5 + 31467181 = 31467186
17 + 31467169 = 31467186
19 + 31467167 = 31467186
29 + 31467157 = 31467186
53 + 31467133 = 31467186
59 + 31467127 = 31467186
83 + 31467103 = 31467186
97 + 31467089 = 31467186

Showing the first eight; more decompositions exist.
