Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47508, here are decompositions:

7 + 47501 = 47508
11 + 47497 = 47508
17 + 47491 = 47508
67 + 47441 = 47508
89 + 47419 = 47508
101 + 47407 = 47508
127 + 47381 = 47508
157 + 47351 = 47508

Showing the first eight; more decompositions exist.
