Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553048, here are decompositions:

31 + 31553017 = 31553048
157 + 31552891 = 31553048
367 + 31552681 = 31553048
409 + 31552639 = 31553048
619 + 31552429 = 31553048
661 + 31552387 = 31553048
739 + 31552309 = 31553048
811 + 31552237 = 31553048

Showing the first eight; more decompositions exist.
