Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553044, here are decompositions:

23 + 31553021 = 31553044
101 + 31552943 = 31553044
137 + 31552907 = 31553044
191 + 31552853 = 31553044
197 + 31552847 = 31553044
227 + 31552817 = 31553044
311 + 31552733 = 31553044
317 + 31552727 = 31553044

Showing the first eight; more decompositions exist.
