Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023538, here are decompositions:

17 + 1023521 = 1023538
71 + 1023467 = 1023538
149 + 1023389 = 1023538
227 + 1023311 = 1023538
239 + 1023299 = 1023538
281 + 1023257 = 1023538
311 + 1023227 = 1023538
317 + 1023221 = 1023538

Showing the first eight; more decompositions exist.
