Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12972, here are decompositions:

5 + 12967 = 12972
13 + 12959 = 12972
19 + 12953 = 12972
31 + 12941 = 12972
53 + 12919 = 12972
61 + 12911 = 12972
73 + 12899 = 12972
79 + 12893 = 12972

Showing the first eight; more decompositions exist.
