Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466438, here are decompositions:

37 + 31466401 = 31466438
97 + 31466341 = 31466438
109 + 31466329 = 31466438
151 + 31466287 = 31466438
181 + 31466257 = 31466438
331 + 31466107 = 31466438
337 + 31466101 = 31466438
349 + 31466089 = 31466438

Showing the first eight; more decompositions exist.
