Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558846, here are decompositions:

3 + 31558843 = 31558846
23 + 31558823 = 31558846
47 + 31558799 = 31558846
113 + 31558733 = 31558846
173 + 31558673 = 31558846
197 + 31558649 = 31558846
227 + 31558619 = 31558846
239 + 31558607 = 31558846

Showing the first eight; more decompositions exist.
