Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47290, here are decompositions:

3 + 47287 = 47290
11 + 47279 = 47290
53 + 47237 = 47290
83 + 47207 = 47290
101 + 47189 = 47290
167 + 47123 = 47290
179 + 47111 = 47290
197 + 47093 = 47290

Showing the first eight; more decompositions exist.
