Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554836, here are decompositions:

7 + 31554829 = 31554836
13 + 31554823 = 31554836
97 + 31554739 = 31554836
127 + 31554709 = 31554836
199 + 31554637 = 31554836
223 + 31554613 = 31554836
373 + 31554463 = 31554836
499 + 31554337 = 31554836

Showing the first eight; more decompositions exist.
