Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13030, here are decompositions:

23 + 13007 = 13030
29 + 13001 = 13030
47 + 12983 = 13030
71 + 12959 = 13030
89 + 12941 = 13030
107 + 12923 = 13030
113 + 12917 = 13030
131 + 12899 = 13030

Showing the first eight; more decompositions exist.
