Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120786, here are decompositions:

7 + 120779 = 120786
19 + 120767 = 120786
23 + 120763 = 120786
37 + 120749 = 120786
47 + 120739 = 120786
73 + 120713 = 120786
97 + 120689 = 120786
109 + 120677 = 120786

Showing the first eight; more decompositions exist.
