Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558926, here are decompositions:

29 + 31558897 = 31558926
43 + 31558883 = 31558926
67 + 31558859 = 31558926
79 + 31558847 = 31558926
83 + 31558843 = 31558926
103 + 31558823 = 31558926
107 + 31558819 = 31558926
127 + 31558799 = 31558926

Showing the first eight; more decompositions exist.
