Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47972, here are decompositions:

3 + 47969 = 47972
61 + 47911 = 47972
103 + 47869 = 47972
163 + 47809 = 47972
181 + 47791 = 47972
193 + 47779 = 47972
229 + 47743 = 47972
271 + 47701 = 47972

Showing the first eight; more decompositions exist.
