Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992840, here are decompositions:

31 + 992809 = 992840
103 + 992737 = 992840
139 + 992701 = 992840
151 + 992689 = 992840
181 + 992659 = 992840
379 + 992461 = 992840
523 + 992317 = 992840
571 + 992269 = 992840

Showing the first eight; more decompositions exist.
