Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55428, here are decompositions:

17 + 55411 = 55428
29 + 55399 = 55428
47 + 55381 = 55428
89 + 55339 = 55428
97 + 55331 = 55428
137 + 55291 = 55428
179 + 55249 = 55428
199 + 55229 = 55428

Showing the first eight; more decompositions exist.
