Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55500, here are decompositions:

13 + 55487 = 55500
31 + 55469 = 55500
43 + 55457 = 55500
59 + 55441 = 55500
61 + 55439 = 55500
89 + 55411 = 55500
101 + 55399 = 55500
127 + 55373 = 55500

Showing the first eight; more decompositions exist.
