Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47538, here are decompositions:

5 + 47533 = 47538
11 + 47527 = 47538
17 + 47521 = 47538
31 + 47507 = 47538
37 + 47501 = 47538
41 + 47497 = 47538
47 + 47491 = 47538
79 + 47459 = 47538

Showing the first eight; more decompositions exist.
