Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045550, here are decompositions:

3 + 1045547 = 1045550
7 + 1045543 = 1045550
43 + 1045507 = 1045550
127 + 1045423 = 1045550
139 + 1045411 = 1045550
157 + 1045393 = 1045550
229 + 1045321 = 1045550
241 + 1045309 = 1045550

Showing the first eight; more decompositions exist.
