Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992578, here are decompositions:

17 + 992561 = 992578
29 + 992549 = 992578
137 + 992441 = 992578
149 + 992429 = 992578
269 + 992309 = 992578
311 + 992267 = 992578
347 + 992231 = 992578
359 + 992219 = 992578

Showing the first eight; more decompositions exist.
