Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554792, here are decompositions:

43 + 31554749 = 31554792
53 + 31554739 = 31554792
83 + 31554709 = 31554792
151 + 31554641 = 31554792
173 + 31554619 = 31554792
179 + 31554613 = 31554792
223 + 31554569 = 31554792
251 + 31554541 = 31554792

Showing the first eight; more decompositions exist.
