Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55512, here are decompositions:

11 + 55501 = 55512
43 + 55469 = 55512
71 + 55441 = 55512
73 + 55439 = 55512
101 + 55411 = 55512
113 + 55399 = 55512
131 + 55381 = 55512
139 + 55373 = 55512

Showing the first eight; more decompositions exist.
