Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992290, here are decompositions:

23 + 992267 = 992290
41 + 992249 = 992290
59 + 992231 = 992290
71 + 992219 = 992290
107 + 992183 = 992290
137 + 992153 = 992290
149 + 992141 = 992290
179 + 992111 = 992290

Showing the first eight; more decompositions exist.
