Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045430, here are decompositions:

3 + 1045427 = 1045430
7 + 1045423 = 1045430
19 + 1045411 = 1045430
37 + 1045393 = 1045430
109 + 1045321 = 1045430
157 + 1045273 = 1045430
193 + 1045237 = 1045430
277 + 1045153 = 1045430

Showing the first eight; more decompositions exist.
