Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67786, here are decompositions:

3 + 67783 = 67786
23 + 67763 = 67786
29 + 67757 = 67786
53 + 67733 = 67786
107 + 67679 = 67786
167 + 67619 = 67786
179 + 67607 = 67786
197 + 67589 = 67786

Showing the first eight; more decompositions exist.
