Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467142, here are decompositions:

53 + 31467089 = 31467142
59 + 31467083 = 31467142
71 + 31467071 = 31467142
131 + 31467011 = 31467142
149 + 31466993 = 31467142
173 + 31466969 = 31467142
191 + 31466951 = 31467142
269 + 31466873 = 31467142

Showing the first eight; more decompositions exist.
