Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024540, here are decompositions:

17 + 1024523 = 1024540
29 + 1024511 = 1024540
59 + 1024481 = 1024540
107 + 1024433 = 1024540
113 + 1024427 = 1024540
149 + 1024391 = 1024540
227 + 1024313 = 1024540
233 + 1024307 = 1024540

Showing the first eight; more decompositions exist.
