Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13032, here are decompositions:

23 + 13009 = 13032
29 + 13003 = 13032
31 + 13001 = 13032
53 + 12979 = 13032
59 + 12973 = 13032
73 + 12959 = 13032
79 + 12953 = 13032
109 + 12923 = 13032

Showing the first eight; more decompositions exist.
