Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021736, here are decompositions:

73 + 1021663 = 1021736
109 + 1021627 = 1021736
307 + 1021429 = 1021736
349 + 1021387 = 1021736
367 + 1021369 = 1021736
409 + 1021327 = 1021736
433 + 1021303 = 1021736
439 + 1021297 = 1021736

Showing the first eight; more decompositions exist.
