Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558024, here are decompositions:

5 + 31558019 = 31558024
11 + 31558013 = 31558024
41 + 31557983 = 31558024
53 + 31557971 = 31558024
167 + 31557857 = 31558024
191 + 31557833 = 31558024
233 + 31557791 = 31558024
263 + 31557761 = 31558024

Showing the first eight; more decompositions exist.
