Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76840, here are decompositions:

3 + 76837 = 76840
11 + 76829 = 76840
59 + 76781 = 76840
83 + 76757 = 76840
107 + 76733 = 76840
167 + 76673 = 76840
173 + 76667 = 76840
191 + 76649 = 76840

Showing the first eight; more decompositions exist.
