Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558326, here are decompositions:

5 + 31558321 = 31558326
17 + 31558309 = 31558326
43 + 31558283 = 31558326
73 + 31558253 = 31558326
97 + 31558229 = 31558326
103 + 31558223 = 31558326
127 + 31558199 = 31558326
139 + 31558187 = 31558326

Showing the first eight; more decompositions exist.
