Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8550, here are decompositions:

7 + 8543 = 8550
11 + 8539 = 8550
13 + 8537 = 8550
23 + 8527 = 8550
29 + 8521 = 8550
37 + 8513 = 8550
83 + 8467 = 8550
89 + 8461 = 8550

Showing the first eight; more decompositions exist.
