Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30972, here are decompositions:

23 + 30949 = 30972
31 + 30941 = 30972
41 + 30931 = 30972
61 + 30911 = 30972
79 + 30893 = 30972
101 + 30871 = 30972
103 + 30869 = 30972
113 + 30859 = 30972

Showing the first eight; more decompositions exist.
