Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553896, here are decompositions:

29 + 31553867 = 31553896
89 + 31553807 = 31553896
113 + 31553783 = 31553896
137 + 31553759 = 31553896
167 + 31553729 = 31553896
233 + 31553663 = 31553896
443 + 31553453 = 31553896
509 + 31553387 = 31553896

Showing the first eight; more decompositions exist.
