Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55000, here are decompositions:

17 + 54983 = 55000
41 + 54959 = 55000
59 + 54941 = 55000
83 + 54917 = 55000
131 + 54869 = 55000
149 + 54851 = 55000
167 + 54833 = 55000
227 + 54773 = 55000

Showing the first eight; more decompositions exist.
