Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045390, here are decompositions:

23 + 1045367 = 1045390
41 + 1045349 = 1045390
83 + 1045307 = 1045390
113 + 1045277 = 1045390
149 + 1045241 = 1045390
167 + 1045223 = 1045390
191 + 1045199 = 1045390
197 + 1045193 = 1045390

Showing the first eight; more decompositions exist.
