Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76830, here are decompositions:

11 + 76819 = 76830
29 + 76801 = 76830
53 + 76777 = 76830
59 + 76771 = 76830
73 + 76757 = 76830
97 + 76733 = 76830
113 + 76717 = 76830
151 + 76679 = 76830

Showing the first eight; more decompositions exist.
