Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30706, here are decompositions:

3 + 30703 = 30706
17 + 30689 = 30706
29 + 30677 = 30706
113 + 30593 = 30706
149 + 30557 = 30706
167 + 30539 = 30706
197 + 30509 = 30706
239 + 30467 = 30706

Showing the first eight; more decompositions exist.
