Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13090, here are decompositions:

41 + 13049 = 13090
47 + 13043 = 13090
53 + 13037 = 13090
83 + 13007 = 13090
89 + 13001 = 13090
107 + 12983 = 13090
131 + 12959 = 13090
137 + 12953 = 13090

Showing the first eight; more decompositions exist.
