Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2150, here are decompositions:

7 + 2143 = 2150
13 + 2137 = 2150
19 + 2131 = 2150
37 + 2113 = 2150
61 + 2089 = 2150
67 + 2083 = 2150
97 + 2053 = 2150
139 + 2011 = 2150

Showing the first eight; more decompositions exist.
