Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044290, here are decompositions:

3 + 1044287 = 1044290
7 + 1044283 = 1044290
19 + 1044271 = 1044290
43 + 1044247 = 1044290
73 + 1044217 = 1044290
97 + 1044193 = 1044290
103 + 1044187 = 1044290
109 + 1044181 = 1044290

Showing the first eight; more decompositions exist.
