Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559026, here are decompositions:

29 + 31558997 = 31559026
53 + 31558973 = 31559026
167 + 31558859 = 31559026
179 + 31558847 = 31559026
227 + 31558799 = 31559026
293 + 31558733 = 31559026
353 + 31558673 = 31559026
419 + 31558607 = 31559026

Showing the first eight; more decompositions exist.
