Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554010, here are decompositions:

17 + 31553993 = 31554010
23 + 31553987 = 31554010
107 + 31553903 = 31554010
227 + 31553783 = 31554010
233 + 31553777 = 31554010
251 + 31553759 = 31554010
281 + 31553729 = 31554010
347 + 31553663 = 31554010

Showing the first eight; more decompositions exist.
