Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30700, here are decompositions:

3 + 30697 = 30700
11 + 30689 = 30700
23 + 30677 = 30700
29 + 30671 = 30700
107 + 30593 = 30700
191 + 30509 = 30700
233 + 30467 = 30700
251 + 30449 = 30700

Showing the first eight; more decompositions exist.
