Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55798, here are decompositions:

5 + 55793 = 55798
11 + 55787 = 55798
101 + 55697 = 55798
107 + 55691 = 55798
131 + 55667 = 55798
137 + 55661 = 55798
167 + 55631 = 55798
179 + 55619 = 55798

Showing the first eight; more decompositions exist.
