Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574514, here are decompositions:

7 + 31574507 = 31574514
17 + 31574497 = 31574514
47 + 31574467 = 31574514
61 + 31574453 = 31574514
71 + 31574443 = 31574514
151 + 31574363 = 31574514
211 + 31574303 = 31574514
281 + 31574233 = 31574514

Showing the first eight; more decompositions exist.
