Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27972, here are decompositions:

5 + 27967 = 27972
11 + 27961 = 27972
19 + 27953 = 27972
29 + 27943 = 27972
31 + 27941 = 27972
53 + 27919 = 27972
71 + 27901 = 27972
79 + 27893 = 27972

Showing the first eight; more decompositions exist.
