Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55562, here are decompositions:

61 + 55501 = 55562
151 + 55411 = 55562
163 + 55399 = 55562
181 + 55381 = 55562
211 + 55351 = 55562
223 + 55339 = 55562
229 + 55333 = 55562
271 + 55291 = 55562

Showing the first eight; more decompositions exist.
