Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021594, here are decompositions:

17 + 1021577 = 1021594
23 + 1021571 = 1021594
53 + 1021541 = 1021594
107 + 1021487 = 1021594
131 + 1021463 = 1021594
137 + 1021457 = 1021594
191 + 1021403 = 1021594
227 + 1021367 = 1021594

Showing the first eight; more decompositions exist.
