Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567084, here are decompositions:

41 + 31567043 = 31567084
173 + 31566911 = 31567084
257 + 31566827 = 31567084
281 + 31566803 = 31567084
347 + 31566737 = 31567084
557 + 31566527 = 31567084
587 + 31566497 = 31567084
641 + 31566443 = 31567084

Showing the first eight; more decompositions exist.
