Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553776, here are decompositions:

17 + 31553759 = 31553776
47 + 31553729 = 31553776
113 + 31553663 = 31553776
167 + 31553609 = 31553776
257 + 31553519 = 31553776
389 + 31553387 = 31553776
503 + 31553273 = 31553776
557 + 31553219 = 31553776

Showing the first eight; more decompositions exist.
