Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024538, here are decompositions:

61 + 1024477 = 1024538
127 + 1024411 = 1024538
139 + 1024399 = 1024538
181 + 1024357 = 1024538
199 + 1024339 = 1024538
211 + 1024327 = 1024538
331 + 1024207 = 1024538
349 + 1024189 = 1024538

Showing the first eight; more decompositions exist.
