Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553008, here are decompositions:

89 + 31552919 = 31553008
101 + 31552907 = 31553008
191 + 31552817 = 31553008
281 + 31552727 = 31553008
419 + 31552589 = 31553008
521 + 31552487 = 31553008
587 + 31552421 = 31553008
797 + 31552211 = 31553008

Showing the first eight; more decompositions exist.
