Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553974, here are decompositions:

71 + 31553903 = 31553974
107 + 31553867 = 31553974
167 + 31553807 = 31553974
173 + 31553801 = 31553974
191 + 31553783 = 31553974
197 + 31553777 = 31553974
311 + 31553663 = 31553974
521 + 31553453 = 31553974

Showing the first eight; more decompositions exist.
