Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972822, here are decompositions:

23 + 972799 = 972822
29 + 972793 = 972822
101 + 972721 = 972822
139 + 972683 = 972822
173 + 972649 = 972822
199 + 972623 = 972822
211 + 972611 = 972822
223 + 972599 = 972822

Showing the first eight; more decompositions exist.
