Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553054, here are decompositions:

37 + 31553017 = 31553054
163 + 31552891 = 31553054
223 + 31552831 = 31553054
307 + 31552747 = 31553054
373 + 31552681 = 31553054
433 + 31552621 = 31553054
661 + 31552393 = 31553054
751 + 31552303 = 31553054

Showing the first eight; more decompositions exist.
