Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55530, here are decompositions:

19 + 55511 = 55530
29 + 55501 = 55530
43 + 55487 = 55530
61 + 55469 = 55530
73 + 55457 = 55530
89 + 55441 = 55530
131 + 55399 = 55530
149 + 55381 = 55530

Showing the first eight; more decompositions exist.
