Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627852, here are decompositions:

41 + 31627811 = 31627852
59 + 31627793 = 31627852
89 + 31627763 = 31627852
101 + 31627751 = 31627852
131 + 31627721 = 31627852
251 + 31627601 = 31627852
293 + 31627559 = 31627852
461 + 31627391 = 31627852

Showing the first eight; more decompositions exist.
