Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454350, here are decompositions:

29 + 31454321 = 31454350
101 + 31454249 = 31454350
131 + 31454219 = 31454350
149 + 31454201 = 31454350
227 + 31454123 = 31454350
233 + 31454117 = 31454350
269 + 31454081 = 31454350
353 + 31453997 = 31454350

Showing the first eight; more decompositions exist.
