Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28448, here are decompositions:

19 + 28429 = 28448
37 + 28411 = 28448
61 + 28387 = 28448
97 + 28351 = 28448
139 + 28309 = 28448
151 + 28297 = 28448
229 + 28219 = 28448
337 + 28111 = 28448

Showing the first eight; more decompositions exist.
