Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454260, here are decompositions:

11 + 31454249 = 31454260
41 + 31454219 = 31454260
59 + 31454201 = 31454260
113 + 31454147 = 31454260
137 + 31454123 = 31454260
179 + 31454081 = 31454260
263 + 31453997 = 31454260
269 + 31453991 = 31454260

Showing the first eight; more decompositions exist.
