Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559008, here are decompositions:

11 + 31558997 = 31559008
149 + 31558859 = 31559008
359 + 31558649 = 31559008
389 + 31558619 = 31559008
401 + 31558607 = 31559008
479 + 31558529 = 31559008
617 + 31558391 = 31559008
797 + 31558211 = 31559008

Showing the first eight; more decompositions exist.
