Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553926, here are decompositions:

23 + 31553903 = 31553926
59 + 31553867 = 31553926
149 + 31553777 = 31553926
167 + 31553759 = 31553926
197 + 31553729 = 31553926
263 + 31553663 = 31553926
317 + 31553609 = 31553926
557 + 31553369 = 31553926

Showing the first eight; more decompositions exist.
