Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572514, here are decompositions:

3 + 31572511 = 31572514
53 + 31572461 = 31572514
101 + 31572413 = 31572514
167 + 31572347 = 31572514
173 + 31572341 = 31572514
191 + 31572323 = 31572514
251 + 31572263 = 31572514
293 + 31572221 = 31572514

Showing the first eight; more decompositions exist.
