Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2140, here are decompositions:

3 + 2137 = 2140
11 + 2129 = 2140
29 + 2111 = 2140
41 + 2099 = 2140
53 + 2087 = 2140
59 + 2081 = 2140
71 + 2069 = 2140
101 + 2039 = 2140

Showing the first eight; more decompositions exist.
