Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558294, here are decompositions:

11 + 31558283 = 31558294
41 + 31558253 = 31558294
71 + 31558223 = 31558294
83 + 31558211 = 31558294
107 + 31558187 = 31558294
113 + 31558181 = 31558294
167 + 31558127 = 31558294
281 + 31558013 = 31558294

Showing the first eight; more decompositions exist.
