Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527514, here are decompositions:

17 + 31527497 = 31527514
23 + 31527491 = 31527514
101 + 31527413 = 31527514
107 + 31527407 = 31527514
191 + 31527323 = 31527514
197 + 31527317 = 31527514
281 + 31527233 = 31527514
383 + 31527131 = 31527514

Showing the first eight; more decompositions exist.
