Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024280, here are decompositions:

3 + 1024277 = 1024280
31 + 1024249 = 1024280
73 + 1024207 = 1024280
97 + 1024183 = 1024280
109 + 1024171 = 1024280
181 + 1024099 = 1024280
193 + 1024087 = 1024280
307 + 1023973 = 1024280

Showing the first eight; more decompositions exist.
