Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980442, here are decompositions:

11 + 980431 = 980442
19 + 980423 = 980442
41 + 980401 = 980442
79 + 980363 = 980442
149 + 980293 = 980442
181 + 980261 = 980442
193 + 980249 = 980442
223 + 980219 = 980442

Showing the first eight; more decompositions exist.
