Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467144, here are decompositions:

11 + 31467133 = 31467144
17 + 31467127 = 31467144
41 + 31467103 = 31467144
61 + 31467083 = 31467144
73 + 31467071 = 31467144
151 + 31466993 = 31467144
167 + 31466977 = 31467144
193 + 31466951 = 31467144

Showing the first eight; more decompositions exist.
