Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30844, here are decompositions:

3 + 30841 = 30844
5 + 30839 = 30844
41 + 30803 = 30844
71 + 30773 = 30844
131 + 30713 = 30844
137 + 30707 = 30844
167 + 30677 = 30844
173 + 30671 = 30844

Showing the first eight; more decompositions exist.
