Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590836, here are decompositions:

3 + 31590833 = 31590836
73 + 31590763 = 31590836
97 + 31590739 = 31590836
103 + 31590733 = 31590836
337 + 31590499 = 31590836
349 + 31590487 = 31590836
367 + 31590469 = 31590836
373 + 31590463 = 31590836

Showing the first eight; more decompositions exist.
