Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554022, here are decompositions:

11 + 31554011 = 31554022
29 + 31553993 = 31554022
239 + 31553783 = 31554022
263 + 31553759 = 31554022
293 + 31553729 = 31554022
359 + 31553663 = 31554022
503 + 31553519 = 31554022
569 + 31553453 = 31554022

Showing the first eight; more decompositions exist.
