Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76842, here are decompositions:

5 + 76837 = 76842
11 + 76831 = 76842
13 + 76829 = 76842
23 + 76819 = 76842
41 + 76801 = 76842
61 + 76781 = 76842
71 + 76771 = 76842
89 + 76753 = 76842

Showing the first eight; more decompositions exist.
