Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558096, here are decompositions:

23 + 31558073 = 31558096
47 + 31558049 = 31558096
83 + 31558013 = 31558096
113 + 31557983 = 31558096
137 + 31557959 = 31558096
239 + 31557857 = 31558096
263 + 31557833 = 31558096
347 + 31557749 = 31558096

Showing the first eight; more decompositions exist.
