Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558834, here are decompositions:

3 + 31558831 = 31558834
11 + 31558823 = 31558834
101 + 31558733 = 31558834
227 + 31558607 = 31558834
401 + 31558433 = 31558834
443 + 31558391 = 31558834
647 + 31558187 = 31558834
653 + 31558181 = 31558834

Showing the first eight; more decompositions exist.
