Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558276, here are decompositions:

23 + 31558253 = 31558276
47 + 31558229 = 31558276
53 + 31558223 = 31558276
89 + 31558187 = 31558276
107 + 31558169 = 31558276
149 + 31558127 = 31558276
227 + 31558049 = 31558276
257 + 31558019 = 31558276

Showing the first eight; more decompositions exist.
