Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9538, here are decompositions:

5 + 9533 = 9538
17 + 9521 = 9538
41 + 9497 = 9538
47 + 9491 = 9538
59 + 9479 = 9538
71 + 9467 = 9538
101 + 9437 = 9538
107 + 9431 = 9538

Showing the first eight; more decompositions exist.
