Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55920, here are decompositions:

17 + 55903 = 55920
19 + 55901 = 55920
23 + 55897 = 55920
31 + 55889 = 55920
71 + 55849 = 55920
83 + 55837 = 55920
97 + 55823 = 55920
101 + 55819 = 55920

Showing the first eight; more decompositions exist.
