Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11922, here are decompositions:

13 + 11909 = 11922
19 + 11903 = 11922
59 + 11863 = 11922
83 + 11839 = 11922
89 + 11833 = 11922
101 + 11821 = 11922
109 + 11813 = 11922
139 + 11783 = 11922

Showing the first eight; more decompositions exist.
