Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453588, here are decompositions:

11 + 31453577 = 31453588
17 + 31453571 = 31453588
59 + 31453529 = 31453588
167 + 31453421 = 31453588
197 + 31453391 = 31453588
227 + 31453361 = 31453588
347 + 31453241 = 31453588
431 + 31453157 = 31453588

Showing the first eight; more decompositions exist.
