Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005822, here are decompositions:

61 + 1005761 = 1005822
71 + 1005751 = 1005822
113 + 1005709 = 1005822
179 + 1005643 = 1005822
229 + 1005593 = 1005822
241 + 1005581 = 1005822
269 + 1005553 = 1005822
271 + 1005551 = 1005822

Showing the first eight; more decompositions exist.
