Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550892, here are decompositions:

13 + 31550879 = 31550892
41 + 31550851 = 31550892
59 + 31550833 = 31550892
89 + 31550803 = 31550892
101 + 31550791 = 31550892
181 + 31550711 = 31550892
193 + 31550699 = 31550892
211 + 31550681 = 31550892

Showing the first eight; more decompositions exist.
