Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553534, here are decompositions:

7 + 31553527 = 31553534
31 + 31553503 = 31553534
151 + 31553383 = 31553534
373 + 31553161 = 31553534
457 + 31553077 = 31553534
643 + 31552891 = 31553534
787 + 31552747 = 31553534
853 + 31552681 = 31553534

Showing the first eight; more decompositions exist.
