Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619448, here are decompositions:

41 + 31619407 = 31619448
59 + 31619389 = 31619448
61 + 31619387 = 31619448
89 + 31619359 = 31619448
137 + 31619311 = 31619448
167 + 31619281 = 31619448
181 + 31619267 = 31619448
191 + 31619257 = 31619448

Showing the first eight; more decompositions exist.
