Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467132, here are decompositions:

5 + 31467127 = 31467132
29 + 31467103 = 31467132
43 + 31467089 = 31467132
61 + 31467071 = 31467132
139 + 31466993 = 31467132
163 + 31466969 = 31467132
181 + 31466951 = 31467132
199 + 31466933 = 31467132

Showing the first eight; more decompositions exist.
