Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558254, here are decompositions:

31 + 31558223 = 31558254
43 + 31558211 = 31558254
47 + 31558207 = 31558254
67 + 31558187 = 31558254
73 + 31558181 = 31558254
107 + 31558147 = 31558254
127 + 31558127 = 31558254
173 + 31558081 = 31558254

Showing the first eight; more decompositions exist.
