Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11972, here are decompositions:

3 + 11969 = 11972
13 + 11959 = 11972
19 + 11953 = 11972
31 + 11941 = 11972
109 + 11863 = 11972
139 + 11833 = 11972
151 + 11821 = 11972
193 + 11779 = 11972

Showing the first eight; more decompositions exist.
