Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554726, here are decompositions:

17 + 31554709 = 31554726
59 + 31554667 = 31554726
67 + 31554659 = 31554726
89 + 31554637 = 31554726
107 + 31554619 = 31554726
109 + 31554617 = 31554726
113 + 31554613 = 31554726
157 + 31554569 = 31554726

Showing the first eight; more decompositions exist.
