Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553744, here are decompositions:

37 + 31553707 = 31553744
73 + 31553671 = 31553744
127 + 31553617 = 31553744
241 + 31553503 = 31553744
727 + 31553017 = 31553744
853 + 31552891 = 31553744
997 + 31552747 = 31553744
1051 + 31552693 = 31553744

Showing the first eight; more decompositions exist.
