Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553836, here are decompositions:

3 + 31553833 = 31553836
29 + 31553807 = 31553836
53 + 31553783 = 31553836
59 + 31553777 = 31553836
107 + 31553729 = 31553836
173 + 31553663 = 31553836
227 + 31553609 = 31553836
317 + 31553519 = 31553836

Showing the first eight; more decompositions exist.
