Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021444, here are decompositions:

3 + 1021441 = 1021444
41 + 1021403 = 1021444
71 + 1021373 = 1021444
113 + 1021331 = 1021444
173 + 1021271 = 1021444
191 + 1021253 = 1021444
227 + 1021217 = 1021444
317 + 1021127 = 1021444

Showing the first eight; more decompositions exist.
