Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024520, here are decompositions:

43 + 1024477 = 1024520
109 + 1024411 = 1024520
163 + 1024357 = 1024520
181 + 1024339 = 1024520
193 + 1024327 = 1024520
199 + 1024321 = 1024520
271 + 1024249 = 1024520
313 + 1024207 = 1024520

Showing the first eight; more decompositions exist.
