Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558324, here are decompositions:

3 + 31558321 = 31558324
41 + 31558283 = 31558324
71 + 31558253 = 31558324
101 + 31558223 = 31558324
113 + 31558211 = 31558324
137 + 31558187 = 31558324
191 + 31558133 = 31558324
197 + 31558127 = 31558324

Showing the first eight; more decompositions exist.
