Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55580, here are decompositions:

79 + 55501 = 55580
139 + 55441 = 55580
181 + 55399 = 55580
199 + 55381 = 55580
229 + 55351 = 55580
241 + 55339 = 55580
331 + 55249 = 55580
337 + 55243 = 55580

Showing the first eight; more decompositions exist.
