Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30556, here are decompositions:

3 + 30553 = 30556
17 + 30539 = 30556
47 + 30509 = 30556
59 + 30497 = 30556
89 + 30467 = 30556
107 + 30449 = 30556
167 + 30389 = 30556
233 + 30323 = 30556

Showing the first eight; more decompositions exist.
