Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9580, here are decompositions:

29 + 9551 = 9580
41 + 9539 = 9580
47 + 9533 = 9580
59 + 9521 = 9580
83 + 9497 = 9580
89 + 9491 = 9580
101 + 9479 = 9580
107 + 9473 = 9580

Showing the first eight; more decompositions exist.
