Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553874, here are decompositions:

7 + 31553867 = 31553874
41 + 31553833 = 31553874
67 + 31553807 = 31553874
71 + 31553803 = 31553874
73 + 31553801 = 31553874
97 + 31553777 = 31553874
113 + 31553761 = 31553874
167 + 31553707 = 31553874

Showing the first eight; more decompositions exist.
