Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554616, here are decompositions:

3 + 31554613 = 31554616
47 + 31554569 = 31554616
89 + 31554527 = 31554616
167 + 31554449 = 31554616
809 + 31553807 = 31554616
839 + 31553777 = 31554616
857 + 31553759 = 31554616
887 + 31553729 = 31554616

Showing the first eight; more decompositions exist.
