Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467100, here are decompositions:

11 + 31467089 = 31467100
17 + 31467083 = 31467100
29 + 31467071 = 31467100
89 + 31467011 = 31467100
101 + 31466999 = 31467100
107 + 31466993 = 31467100
131 + 31466969 = 31467100
149 + 31466951 = 31467100

Showing the first eight; more decompositions exist.
