Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55856, here are decompositions:

7 + 55849 = 55856
13 + 55843 = 55856
19 + 55837 = 55856
37 + 55819 = 55856
43 + 55813 = 55856
139 + 55717 = 55856
193 + 55663 = 55856
223 + 55633 = 55856

Showing the first eight; more decompositions exist.
