Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627804, here are decompositions:

3 + 31627801 = 31627804
11 + 31627793 = 31627804
41 + 31627763 = 31627804
53 + 31627751 = 31627804
83 + 31627721 = 31627804
227 + 31627577 = 31627804
293 + 31627511 = 31627804
431 + 31627373 = 31627804

Showing the first eight; more decompositions exist.
