Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466300, here are decompositions:

13 + 31466287 = 31466300
37 + 31466263 = 31466300
43 + 31466257 = 31466300
67 + 31466233 = 31466300
79 + 31466221 = 31466300
127 + 31466173 = 31466300
157 + 31466143 = 31466300
163 + 31466137 = 31466300

Showing the first eight; more decompositions exist.
