Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553934, here are decompositions:

31 + 31553903 = 31553934
67 + 31553867 = 31553934
101 + 31553833 = 31553934
127 + 31553807 = 31553934
131 + 31553803 = 31553934
151 + 31553783 = 31553934
157 + 31553777 = 31553934
173 + 31553761 = 31553934

Showing the first eight; more decompositions exist.
