Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552888, here are decompositions:

5 + 31552883 = 31552888
41 + 31552847 = 31552888
71 + 31552817 = 31552888
167 + 31552721 = 31552888
179 + 31552709 = 31552888
401 + 31552487 = 31552888
467 + 31552421 = 31552888
617 + 31552271 = 31552888

Showing the first eight; more decompositions exist.
