Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454338, here are decompositions:

17 + 31454321 = 31454338
89 + 31454249 = 31454338
137 + 31454201 = 31454338
191 + 31454147 = 31454338
257 + 31454081 = 31454338
347 + 31453991 = 31454338
659 + 31453679 = 31454338
761 + 31453577 = 31454338

Showing the first eight; more decompositions exist.
