Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558054, here are decompositions:

5 + 31558049 = 31558054
41 + 31558013 = 31558054
71 + 31557983 = 31558054
83 + 31557971 = 31558054
173 + 31557881 = 31558054
197 + 31557857 = 31558054
263 + 31557791 = 31558054
293 + 31557761 = 31558054

Showing the first eight; more decompositions exist.
