Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558226, here are decompositions:

3 + 31558223 = 31558226
19 + 31558207 = 31558226
79 + 31558147 = 31558226
97 + 31558129 = 31558226
163 + 31558063 = 31558226
229 + 31557997 = 31558226
307 + 31557919 = 31558226
439 + 31557787 = 31558226

Showing the first eight; more decompositions exist.
