Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001822, here are decompositions:

13 + 1001809 = 1001822
79 + 1001743 = 1001822
109 + 1001713 = 1001822
139 + 1001683 = 1001822
163 + 1001659 = 1001822
193 + 1001629 = 1001822
229 + 1001593 = 1001822
271 + 1001551 = 1001822

Showing the first eight; more decompositions exist.
