Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13072, here are decompositions:

23 + 13049 = 13072
29 + 13043 = 13072
71 + 13001 = 13072
89 + 12983 = 13072
113 + 12959 = 13072
131 + 12941 = 13072
149 + 12923 = 13072
173 + 12899 = 13072

Showing the first eight; more decompositions exist.
