Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021492, here are decompositions:

5 + 1021487 = 1021492
29 + 1021463 = 1021492
89 + 1021403 = 1021492
191 + 1021301 = 1021492
233 + 1021259 = 1021492
239 + 1021253 = 1021492
293 + 1021199 = 1021492
401 + 1021091 = 1021492

Showing the first eight; more decompositions exist.
