Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55830, here are decompositions:

7 + 55823 = 55830
11 + 55819 = 55830
13 + 55817 = 55830
17 + 55813 = 55830
23 + 55807 = 55830
31 + 55799 = 55830
37 + 55793 = 55830
43 + 55787 = 55830

Showing the first eight; more decompositions exist.
