Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47242, here are decompositions:

5 + 47237 = 47242
53 + 47189 = 47242
113 + 47129 = 47242
131 + 47111 = 47242
149 + 47093 = 47242
191 + 47051 = 47242
353 + 46889 = 47242
389 + 46853 = 47242

Showing the first eight; more decompositions exist.
