Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186020, here are decompositions:

7 + 186013 = 186020
13 + 186007 = 186020
61 + 185959 = 186020
73 + 185947 = 186020
97 + 185923 = 186020
103 + 185917 = 186020
127 + 185893 = 186020
151 + 185869 = 186020

Showing the first eight; more decompositions exist.
