Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55572, here are decompositions:

31 + 55541 = 55572
43 + 55529 = 55572
61 + 55511 = 55572
71 + 55501 = 55572
103 + 55469 = 55572
131 + 55441 = 55572
173 + 55399 = 55572
191 + 55381 = 55572

Showing the first eight; more decompositions exist.
