Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466426, here are decompositions:

37 + 31466389 = 31466426
97 + 31466329 = 31466426
139 + 31466287 = 31466426
163 + 31466263 = 31466426
193 + 31466233 = 31466426
283 + 31466143 = 31466426
307 + 31466119 = 31466426
337 + 31466089 = 31466426

Showing the first eight; more decompositions exist.
