Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466126, here are decompositions:

7 + 31466119 = 31466126
19 + 31466107 = 31466126
37 + 31466089 = 31466126
73 + 31466053 = 31466126
127 + 31465999 = 31466126
277 + 31465849 = 31466126
337 + 31465789 = 31466126
379 + 31465747 = 31466126

Showing the first eight; more decompositions exist.
