Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55398, here are decompositions:

17 + 55381 = 55398
47 + 55351 = 55398
59 + 55339 = 55398
61 + 55337 = 55398
67 + 55331 = 55398
107 + 55291 = 55398
139 + 55259 = 55398
149 + 55249 = 55398

Showing the first eight; more decompositions exist.
