Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554048, here are decompositions:

5 + 31554043 = 31554048
37 + 31554011 = 31554048
61 + 31553987 = 31554048
181 + 31553867 = 31554048
241 + 31553807 = 31554048
271 + 31553777 = 31554048
389 + 31553659 = 31554048
431 + 31553617 = 31554048

Showing the first eight; more decompositions exist.
