Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11830, here are decompositions:

3 + 11827 = 11830
17 + 11813 = 11830
23 + 11807 = 11830
29 + 11801 = 11830
41 + 11789 = 11830
47 + 11783 = 11830
53 + 11777 = 11830
113 + 11717 = 11830

Showing the first eight; more decompositions exist.
