Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466900, here are decompositions:

7 + 31466893 = 31466900
43 + 31466857 = 31466900
79 + 31466821 = 31466900
109 + 31466791 = 31466900
151 + 31466749 = 31466900
181 + 31466719 = 31466900
193 + 31466707 = 31466900
211 + 31466689 = 31466900

Showing the first eight; more decompositions exist.
