Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045090, here are decompositions:

29 + 1045061 = 1045090
47 + 1045043 = 1045090
149 + 1044941 = 1045090
197 + 1044893 = 1045090
239 + 1044851 = 1045090
251 + 1044839 = 1045090
257 + 1044833 = 1045090
281 + 1044809 = 1045090

Showing the first eight; more decompositions exist.
