Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466100, here are decompositions:

11 + 31466089 = 31466100
37 + 31466063 = 31466100
47 + 31466053 = 31466100
97 + 31466003 = 31466100
101 + 31465999 = 31466100
251 + 31465849 = 31466100
269 + 31465831 = 31466100
271 + 31465829 = 31466100

Showing the first eight; more decompositions exist.
