Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542514, here are decompositions:

5 + 31542509 = 31542514
137 + 31542377 = 31542514
173 + 31542341 = 31542514
191 + 31542323 = 31542514
233 + 31542281 = 31542514
281 + 31542233 = 31542514
317 + 31542197 = 31542514
401 + 31542113 = 31542514

Showing the first eight; more decompositions exist.
