Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554254, here are decompositions:

13 + 31554241 = 31554254
73 + 31554181 = 31554254
181 + 31554073 = 31554254
211 + 31554043 = 31554254
241 + 31554013 = 31554254
271 + 31553983 = 31554254
421 + 31553833 = 31554254
547 + 31553707 = 31554254

Showing the first eight; more decompositions exist.
