Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560532, here are decompositions:

23 + 31560509 = 31560532
131 + 31560401 = 31560532
149 + 31560383 = 31560532
191 + 31560341 = 31560532
233 + 31560299 = 31560532
239 + 31560293 = 31560532
281 + 31560251 = 31560532
293 + 31560239 = 31560532

Showing the first eight; more decompositions exist.
