Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028722, here are decompositions:

41 + 1028681 = 1028722
53 + 1028669 = 1028722
59 + 1028663 = 1028722
251 + 1028471 = 1028722
311 + 1028411 = 1028722
389 + 1028333 = 1028722
419 + 1028303 = 1028722
449 + 1028273 = 1028722

Showing the first eight; more decompositions exist.
