Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553612, here are decompositions:

3 + 31553609 = 31553612
109 + 31553503 = 31553612
229 + 31553383 = 31553612
379 + 31553233 = 31553612
523 + 31553089 = 31553612
613 + 31552999 = 31553612
733 + 31552879 = 31553612
919 + 31552693 = 31553612

Showing the first eight; more decompositions exist.
