Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528524, here are decompositions:

23 + 31528501 = 31528524
73 + 31528451 = 31528524
151 + 31528373 = 31528524
197 + 31528327 = 31528524
211 + 31528313 = 31528524
233 + 31528291 = 31528524
241 + 31528283 = 31528524
257 + 31528267 = 31528524

Showing the first eight; more decompositions exist.
