Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466180, here are decompositions:

7 + 31466173 = 31466180
37 + 31466143 = 31466180
43 + 31466137 = 31466180
61 + 31466119 = 31466180
73 + 31466107 = 31466180
79 + 31466101 = 31466180
127 + 31466053 = 31466180
181 + 31465999 = 31466180

Showing the first eight; more decompositions exist.
