Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467222, here are decompositions:

19 + 31467203 = 31467222
23 + 31467199 = 31467222
41 + 31467181 = 31467222
53 + 31467169 = 31467222
89 + 31467133 = 31467222
139 + 31467083 = 31467222
151 + 31467071 = 31467222
211 + 31467011 = 31467222

Showing the first eight; more decompositions exist.
