Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454424, here are decompositions:

41 + 31454383 = 31454424
47 + 31454377 = 31454424
73 + 31454351 = 31454424
103 + 31454321 = 31454424
223 + 31454201 = 31454424
227 + 31454197 = 31454424
233 + 31454191 = 31454424
263 + 31454161 = 31454424

Showing the first eight; more decompositions exist.
