Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5500, here are decompositions:

17 + 5483 = 5500
23 + 5477 = 5500
29 + 5471 = 5500
59 + 5441 = 5500
83 + 5417 = 5500
101 + 5399 = 5500
107 + 5393 = 5500
113 + 5387 = 5500

Showing the first eight; more decompositions exist.
