Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545948, here are decompositions:

29 + 31545919 = 31545948
47 + 31545901 = 31545948
61 + 31545887 = 31545948
89 + 31545859 = 31545948
107 + 31545841 = 31545948
199 + 31545749 = 31545948
211 + 31545737 = 31545948
281 + 31545667 = 31545948

Showing the first eight; more decompositions exist.
