Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26730, here are decompositions:

7 + 26723 = 26730
13 + 26717 = 26730
17 + 26713 = 26730
19 + 26711 = 26730
29 + 26701 = 26730
31 + 26699 = 26730
37 + 26693 = 26730
43 + 26687 = 26730

Showing the first eight; more decompositions exist.
