Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553024, here are decompositions:

3 + 31553021 = 31553024
7 + 31553017 = 31553024
193 + 31552831 = 31553024
277 + 31552747 = 31553024
331 + 31552693 = 31553024
421 + 31552603 = 31553024
487 + 31552537 = 31553024
631 + 31552393 = 31553024

Showing the first eight; more decompositions exist.
