Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992440, here are decompositions:

3 + 992437 = 992440
11 + 992429 = 992440
23 + 992417 = 992440
47 + 992393 = 992440
83 + 992357 = 992440
131 + 992309 = 992440
173 + 992267 = 992440
191 + 992249 = 992440

Showing the first eight; more decompositions exist.
