Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47428, here are decompositions:

11 + 47417 = 47428
41 + 47387 = 47428
47 + 47381 = 47428
89 + 47339 = 47428
131 + 47297 = 47428
149 + 47279 = 47428
191 + 47237 = 47428
239 + 47189 = 47428

Showing the first eight; more decompositions exist.
