Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55542, here are decompositions:

13 + 55529 = 55542
31 + 55511 = 55542
41 + 55501 = 55542
73 + 55469 = 55542
101 + 55441 = 55542
103 + 55439 = 55542
131 + 55411 = 55542
191 + 55351 = 55542

Showing the first eight; more decompositions exist.
