Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553504, here are decompositions:

271 + 31553233 = 31553504
487 + 31553017 = 31553504
613 + 31552891 = 31553504
673 + 31552831 = 31553504
757 + 31552747 = 31553504
811 + 31552693 = 31553504
823 + 31552681 = 31553504
883 + 31552621 = 31553504

Showing the first eight; more decompositions exist.
