Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454848, here are decompositions:

11 + 31454837 = 31454848
107 + 31454741 = 31454848
167 + 31454681 = 31454848
179 + 31454669 = 31454848
197 + 31454651 = 31454848
599 + 31454249 = 31454848
647 + 31454201 = 31454848
701 + 31454147 = 31454848

Showing the first eight; more decompositions exist.
