Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000822, here are decompositions:

29 + 1000793 = 1000822
59 + 1000763 = 1000822
101 + 1000721 = 1000822
131 + 1000691 = 1000822
233 + 1000589 = 1000822
281 + 1000541 = 1000822
419 + 1000403 = 1000822
509 + 1000313 = 1000822

Showing the first eight; more decompositions exist.
