Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537032, here are decompositions:

5 + 31537027 = 31537032
29 + 31537003 = 31537032
31 + 31537001 = 31537032
41 + 31536991 = 31537032
73 + 31536959 = 31537032
89 + 31536943 = 31537032
211 + 31536821 = 31537032
239 + 31536793 = 31537032

Showing the first eight; more decompositions exist.
