Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553516, here are decompositions:

13 + 31553503 = 31553516
157 + 31553359 = 31553516
283 + 31553233 = 31553516
439 + 31553077 = 31553516
499 + 31553017 = 31553516
769 + 31552747 = 31553516
823 + 31552693 = 31553516
877 + 31552639 = 31553516

Showing the first eight; more decompositions exist.
