Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466246, here are decompositions:

13 + 31466233 = 31466246
73 + 31466173 = 31466246
103 + 31466143 = 31466246
109 + 31466137 = 31466246
127 + 31466119 = 31466246
139 + 31466107 = 31466246
157 + 31466089 = 31466246
193 + 31466053 = 31466246

Showing the first eight; more decompositions exist.
