Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021606, here are decompositions:

29 + 1021577 = 1021606
149 + 1021457 = 1021606
233 + 1021373 = 1021606
239 + 1021367 = 1021606
317 + 1021289 = 1021606
347 + 1021259 = 1021606
353 + 1021253 = 1021606
389 + 1021217 = 1021606

Showing the first eight; more decompositions exist.
