Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466210, here are decompositions:

3 + 31466207 = 31466210
37 + 31466173 = 31466210
67 + 31466143 = 31466210
73 + 31466137 = 31466210
103 + 31466107 = 31466210
109 + 31466101 = 31466210
157 + 31466053 = 31466210
211 + 31465999 = 31466210

Showing the first eight; more decompositions exist.
