Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553892, here are decompositions:

59 + 31553833 = 31553892
89 + 31553803 = 31553892
109 + 31553783 = 31553892
131 + 31553761 = 31553892
163 + 31553729 = 31553892
173 + 31553719 = 31553892
229 + 31553663 = 31553892
233 + 31553659 = 31553892

Showing the first eight; more decompositions exist.
