Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558354, here are decompositions:

17 + 31558337 = 31558354
71 + 31558283 = 31558354
101 + 31558253 = 31558354
131 + 31558223 = 31558354
167 + 31558187 = 31558354
173 + 31558181 = 31558354
227 + 31558127 = 31558354
281 + 31558073 = 31558354

Showing the first eight; more decompositions exist.
