Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466390, here are decompositions:

3 + 31466387 = 31466390
61 + 31466329 = 31466390
103 + 31466287 = 31466390
127 + 31466263 = 31466390
139 + 31466251 = 31466390
157 + 31466233 = 31466390
271 + 31466119 = 31466390
283 + 31466107 = 31466390

Showing the first eight; more decompositions exist.
