Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40830, here are decompositions:

7 + 40823 = 40830
11 + 40819 = 40830
17 + 40813 = 40830
29 + 40801 = 40830
43 + 40787 = 40830
59 + 40771 = 40830
67 + 40763 = 40830
71 + 40759 = 40830

Showing the first eight; more decompositions exist.
