Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021382, here are decompositions:

13 + 1021369 = 1021382
79 + 1021303 = 1021382
139 + 1021243 = 1021382
199 + 1021183 = 1021382
223 + 1021159 = 1021382
409 + 1020973 = 1021382
421 + 1020961 = 1021382
541 + 1020841 = 1021382

Showing the first eight; more decompositions exist.
