Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55568, here are decompositions:

67 + 55501 = 55568
127 + 55441 = 55568
157 + 55411 = 55568
229 + 55339 = 55568
277 + 55291 = 55568
349 + 55219 = 55568
367 + 55201 = 55568
397 + 55171 = 55568

Showing the first eight; more decompositions exist.
