Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627792, here are decompositions:

29 + 31627763 = 31627792
41 + 31627751 = 31627792
71 + 31627721 = 31627792
191 + 31627601 = 31627792
233 + 31627559 = 31627792
281 + 31627511 = 31627792
401 + 31627391 = 31627792
419 + 31627373 = 31627792

Showing the first eight; more decompositions exist.
