Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023648, here are decompositions:

5 + 1023643 = 1023648
47 + 1023601 = 1023648
71 + 1023577 = 1023648
97 + 1023551 = 1023648
107 + 1023541 = 1023648
127 + 1023521 = 1023648
149 + 1023499 = 1023648
181 + 1023467 = 1023648

Showing the first eight; more decompositions exist.
