Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554284, here are decompositions:

43 + 31554241 = 31554284
103 + 31554181 = 31554284
163 + 31554121 = 31554284
211 + 31554073 = 31554284
241 + 31554043 = 31554284
271 + 31554013 = 31554284
523 + 31553761 = 31554284
577 + 31553707 = 31554284

Showing the first eight; more decompositions exist.
