Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623426, here are decompositions:

5 + 31623421 = 31623426
53 + 31623373 = 31623426
83 + 31623343 = 31623426
89 + 31623337 = 31623426
227 + 31623199 = 31623426
257 + 31623169 = 31623426
313 + 31623113 = 31623426
379 + 31623047 = 31623426

Showing the first eight; more decompositions exist.
