Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47550, here are decompositions:

7 + 47543 = 47550
17 + 47533 = 47550
23 + 47527 = 47550
29 + 47521 = 47550
37 + 47513 = 47550
43 + 47507 = 47550
53 + 47497 = 47550
59 + 47491 = 47550

Showing the first eight; more decompositions exist.
