Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467130, here are decompositions:

3 + 31467127 = 31467130
41 + 31467089 = 31467130
47 + 31467083 = 31467130
59 + 31467071 = 31467130
131 + 31466999 = 31467130
137 + 31466993 = 31467130
179 + 31466951 = 31467130
197 + 31466933 = 31467130

Showing the first eight; more decompositions exist.
