Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55570, here are decompositions:

23 + 55547 = 55570
29 + 55541 = 55570
41 + 55529 = 55570
59 + 55511 = 55570
83 + 55487 = 55570
101 + 55469 = 55570
113 + 55457 = 55570
131 + 55439 = 55570

Showing the first eight; more decompositions exist.
