Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13120, here are decompositions:

11 + 13109 = 13120
17 + 13103 = 13120
71 + 13049 = 13120
83 + 13037 = 13120
113 + 13007 = 13120
137 + 12983 = 13120
167 + 12953 = 13120
179 + 12941 = 13120

Showing the first eight; more decompositions exist.
