Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554036, here are decompositions:

23 + 31554013 = 31554036
43 + 31553993 = 31554036
53 + 31553983 = 31554036
229 + 31553807 = 31554036
233 + 31553803 = 31554036
277 + 31553759 = 31554036
307 + 31553729 = 31554036
317 + 31553719 = 31554036

Showing the first eight; more decompositions exist.
