Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045378, here are decompositions:

11 + 1045367 = 1045378
29 + 1045349 = 1045378
71 + 1045307 = 1045378
101 + 1045277 = 1045378
137 + 1045241 = 1045378
149 + 1045229 = 1045378
179 + 1045199 = 1045378
227 + 1045151 = 1045378

Showing the first eight; more decompositions exist.
