Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553774, here are decompositions:

13 + 31553761 = 31553774
67 + 31553707 = 31553774
103 + 31553671 = 31553774
157 + 31553617 = 31553774
271 + 31553503 = 31553774
541 + 31553233 = 31553774
613 + 31553161 = 31553774
757 + 31553017 = 31553774

Showing the first eight; more decompositions exist.
