Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11822, here are decompositions:

43 + 11779 = 11822
79 + 11743 = 11822
103 + 11719 = 11822
229 + 11593 = 11822
271 + 11551 = 11822
331 + 11491 = 11822
379 + 11443 = 11822
439 + 11383 = 11822

Showing the first eight; more decompositions exist.
