Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30730, here are decompositions:

3 + 30727 = 30730
17 + 30713 = 30730
23 + 30707 = 30730
41 + 30689 = 30730
53 + 30677 = 30730
59 + 30671 = 30730
137 + 30593 = 30730
173 + 30557 = 30730

Showing the first eight; more decompositions exist.
