Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30832, here are decompositions:

3 + 30829 = 30832
23 + 30809 = 30832
29 + 30803 = 30832
59 + 30773 = 30832
239 + 30593 = 30832
293 + 30539 = 30832
383 + 30449 = 30832
401 + 30431 = 30832

Showing the first eight; more decompositions exist.
