Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558234, here are decompositions:

5 + 31558229 = 31558234
11 + 31558223 = 31558234
23 + 31558211 = 31558234
47 + 31558187 = 31558234
53 + 31558181 = 31558234
101 + 31558133 = 31558234
107 + 31558127 = 31558234
251 + 31557983 = 31558234

Showing the first eight; more decompositions exist.
