Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8130, here are decompositions:

7 + 8123 = 8130
13 + 8117 = 8130
19 + 8111 = 8130
29 + 8101 = 8130
37 + 8093 = 8130
41 + 8089 = 8130
43 + 8087 = 8130
61 + 8069 = 8130

Showing the first eight; more decompositions exist.
