Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055450, here are decompositions:

13 + 1055437 = 1055450
37 + 1055413 = 1055450
43 + 1055407 = 1055450
79 + 1055371 = 1055450
103 + 1055347 = 1055450
181 + 1055269 = 1055450
199 + 1055251 = 1055450
283 + 1055167 = 1055450

Showing the first eight; more decompositions exist.
