Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500836, here are decompositions:

19 + 31500817 = 31500836
43 + 31500793 = 31500836
277 + 31500559 = 31500836
307 + 31500529 = 31500836
349 + 31500487 = 31500836
373 + 31500463 = 31500836
379 + 31500457 = 31500836
457 + 31500379 = 31500836

Showing the first eight; more decompositions exist.
