Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47240, here are decompositions:

3 + 47237 = 47240
19 + 47221 = 47240
79 + 47161 = 47240
97 + 47143 = 47240
103 + 47137 = 47240
181 + 47059 = 47240
199 + 47041 = 47240
223 + 47017 = 47240

Showing the first eight; more decompositions exist.
