Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558962, here are decompositions:

5 + 31558957 = 31558962
23 + 31558939 = 31558962
79 + 31558883 = 31558962
103 + 31558859 = 31558962
131 + 31558831 = 31558962
139 + 31558823 = 31558962
163 + 31558799 = 31558962
173 + 31558789 = 31558962

Showing the first eight; more decompositions exist.
