Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466166, here are decompositions:

23 + 31466143 = 31466166
29 + 31466137 = 31466166
47 + 31466119 = 31466166
59 + 31466107 = 31466166
103 + 31466063 = 31466166
113 + 31466053 = 31466166
163 + 31466003 = 31466166
167 + 31465999 = 31466166

Showing the first eight; more decompositions exist.
