Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55520, here are decompositions:

19 + 55501 = 55520
79 + 55441 = 55520
109 + 55411 = 55520
139 + 55381 = 55520
181 + 55339 = 55520
229 + 55291 = 55520
271 + 55249 = 55520
277 + 55243 = 55520

Showing the first eight; more decompositions exist.
