Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558444, here are decompositions:

11 + 31558433 = 31558444
53 + 31558391 = 31558444
107 + 31558337 = 31558444
191 + 31558253 = 31558444
233 + 31558211 = 31558444
257 + 31558187 = 31558444
263 + 31558181 = 31558444
311 + 31558133 = 31558444

Showing the first eight; more decompositions exist.
