Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553952, here are decompositions:

149 + 31553803 = 31553952
151 + 31553801 = 31553952
191 + 31553761 = 31553952
193 + 31553759 = 31553952
223 + 31553729 = 31553952
233 + 31553719 = 31553952
281 + 31553671 = 31553952
293 + 31553659 = 31553952

Showing the first eight; more decompositions exist.
