Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15972, here are decompositions:

13 + 15959 = 15972
53 + 15919 = 15972
59 + 15913 = 15972
71 + 15901 = 15972
83 + 15889 = 15972
113 + 15859 = 15972
149 + 15823 = 15972
163 + 15809 = 15972

Showing the first eight; more decompositions exist.
