Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55660, here are decompositions:

29 + 55631 = 55660
41 + 55619 = 55660
71 + 55589 = 55660
113 + 55547 = 55660
131 + 55529 = 55660
149 + 55511 = 55660
173 + 55487 = 55660
191 + 55469 = 55660

Showing the first eight; more decompositions exist.
