Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463426, here are decompositions:

19 + 31463407 = 31463426
37 + 31463389 = 31463426
73 + 31463353 = 31463426
97 + 31463329 = 31463426
109 + 31463317 = 31463426
157 + 31463269 = 31463426
199 + 31463227 = 31463426
223 + 31463203 = 31463426

Showing the first eight; more decompositions exist.
