Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021876, here are decompositions:

83 + 1021793 = 1021876
179 + 1021697 = 1021876
389 + 1021487 = 1021876
419 + 1021457 = 1021876
503 + 1021373 = 1021876
509 + 1021367 = 1021876
587 + 1021289 = 1021876
593 + 1021283 = 1021876

Showing the first eight; more decompositions exist.
