Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86772, here are decompositions:

5 + 86767 = 86772
19 + 86753 = 86772
29 + 86743 = 86772
43 + 86729 = 86772
53 + 86719 = 86772
61 + 86711 = 86772
79 + 86693 = 86772
83 + 86689 = 86772

Showing the first eight; more decompositions exist.
