Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55258, here are decompositions:

29 + 55229 = 55258
41 + 55217 = 55258
131 + 55127 = 55258
149 + 55109 = 55258
179 + 55079 = 55258
197 + 55061 = 55258
257 + 55001 = 55258
317 + 54941 = 55258

Showing the first eight; more decompositions exist.
