Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55618, here are decompositions:

29 + 55589 = 55618
71 + 55547 = 55618
89 + 55529 = 55618
107 + 55511 = 55618
131 + 55487 = 55618
149 + 55469 = 55618
179 + 55439 = 55618
281 + 55337 = 55618

Showing the first eight; more decompositions exist.
