Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47122, here are decompositions:

3 + 47119 = 47122
11 + 47111 = 47122
29 + 47093 = 47122
71 + 47051 = 47122
233 + 46889 = 47122
269 + 46853 = 47122
293 + 46829 = 47122
311 + 46811 = 47122

Showing the first eight; more decompositions exist.
