Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623354, here are decompositions:

11 + 31623343 = 31623354
17 + 31623337 = 31623354
97 + 31623257 = 31623354
131 + 31623223 = 31623354
173 + 31623181 = 31623354
181 + 31623173 = 31623354
233 + 31623121 = 31623354
241 + 31623113 = 31623354

Showing the first eight; more decompositions exist.
