Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021636, here are decompositions:

59 + 1021577 = 1021636
149 + 1021487 = 1021636
173 + 1021463 = 1021636
179 + 1021457 = 1021636
233 + 1021403 = 1021636
263 + 1021373 = 1021636
269 + 1021367 = 1021636
347 + 1021289 = 1021636

Showing the first eight; more decompositions exist.
