Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2120, here are decompositions:

7 + 2113 = 2120
31 + 2089 = 2120
37 + 2083 = 2120
67 + 2053 = 2120
103 + 2017 = 2120
109 + 2011 = 2120
127 + 1993 = 2120
241 + 1879 = 2120

Showing the first eight; more decompositions exist.
