Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558876, here are decompositions:

17 + 31558859 = 31558876
29 + 31558847 = 31558876
53 + 31558823 = 31558876
227 + 31558649 = 31558876
257 + 31558619 = 31558876
269 + 31558607 = 31558876
347 + 31558529 = 31558876
443 + 31558433 = 31558876

Showing the first eight; more decompositions exist.
