Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102448, here are decompositions:

11 + 102437 = 102448
41 + 102407 = 102448
89 + 102359 = 102448
131 + 102317 = 102448
149 + 102299 = 102448
197 + 102251 = 102448
251 + 102197 = 102448
257 + 102191 = 102448

Showing the first eight; more decompositions exist.
