Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626358, here are decompositions:

149 + 31626209 = 31626358
167 + 31626191 = 31626358
191 + 31626167 = 31626358
227 + 31626131 = 31626358
317 + 31626041 = 31626358
347 + 31626011 = 31626358
389 + 31625969 = 31626358
419 + 31625939 = 31626358

Showing the first eight; more decompositions exist.
