Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554056, here are decompositions:

13 + 31554043 = 31554056
43 + 31554013 = 31554056
73 + 31553983 = 31554056
223 + 31553833 = 31554056
337 + 31553719 = 31554056
349 + 31553707 = 31554056
397 + 31553659 = 31554056
439 + 31553617 = 31554056

Showing the first eight; more decompositions exist.
