Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559854, here are decompositions:

3 + 31559851 = 31559854
5 + 31559849 = 31559854
23 + 31559831 = 31559854
41 + 31559813 = 31559854
71 + 31559783 = 31559854
83 + 31559771 = 31559854
167 + 31559687 = 31559854
173 + 31559681 = 31559854

Showing the first eight; more decompositions exist.
