Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605514, here are decompositions:

23 + 31605491 = 31605514
71 + 31605443 = 31605514
107 + 31605407 = 31605514
113 + 31605401 = 31605514
137 + 31605377 = 31605514
251 + 31605263 = 31605514
257 + 31605257 = 31605514
293 + 31605221 = 31605514

Showing the first eight; more decompositions exist.
