Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27830, here are decompositions:

3 + 27827 = 27830
7 + 27823 = 27830
13 + 27817 = 27830
31 + 27799 = 27830
37 + 27793 = 27830
67 + 27763 = 27830
79 + 27751 = 27830
97 + 27733 = 27830

Showing the first eight; more decompositions exist.
