Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30826, here are decompositions:

17 + 30809 = 30826
23 + 30803 = 30826
53 + 30773 = 30826
113 + 30713 = 30826
137 + 30689 = 30826
149 + 30677 = 30826
233 + 30593 = 30826
269 + 30557 = 30826

Showing the first eight; more decompositions exist.
