Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47220, here are decompositions:

13 + 47207 = 47220
31 + 47189 = 47220
59 + 47161 = 47220
71 + 47149 = 47220
73 + 47147 = 47220
83 + 47137 = 47220
97 + 47123 = 47220
101 + 47119 = 47220

Showing the first eight; more decompositions exist.
