Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55406, here are decompositions:

7 + 55399 = 55406
67 + 55339 = 55406
73 + 55333 = 55406
157 + 55249 = 55406
163 + 55243 = 55406
193 + 55213 = 55406
199 + 55207 = 55406
349 + 55057 = 55406

Showing the first eight; more decompositions exist.
