Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12020, here are decompositions:

13 + 12007 = 12020
61 + 11959 = 12020
67 + 11953 = 12020
79 + 11941 = 12020
97 + 11923 = 12020
157 + 11863 = 12020
181 + 11839 = 12020
193 + 11827 = 12020

Showing the first eight; more decompositions exist.
