Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2130, here are decompositions:

17 + 2113 = 2130
19 + 2111 = 2130
31 + 2099 = 2130
41 + 2089 = 2130
43 + 2087 = 2130
47 + 2083 = 2130
61 + 2069 = 2130
67 + 2063 = 2130

Showing the first eight; more decompositions exist.
