Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992428, here are decompositions:

11 + 992417 = 992428
71 + 992357 = 992428
179 + 992249 = 992428
197 + 992231 = 992428
317 + 992111 = 992428
449 + 991979 = 992428
467 + 991961 = 992428
557 + 991871 = 992428

Showing the first eight; more decompositions exist.
