Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55242, here are decompositions:

13 + 55229 = 55242
23 + 55219 = 55242
29 + 55213 = 55242
41 + 55201 = 55242
71 + 55171 = 55242
79 + 55163 = 55242
139 + 55103 = 55242
163 + 55079 = 55242

Showing the first eight; more decompositions exist.
