Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76940, here are decompositions:

67 + 76873 = 76940
103 + 76837 = 76940
109 + 76831 = 76940
139 + 76801 = 76940
163 + 76777 = 76940
223 + 76717 = 76940
337 + 76603 = 76940
379 + 76561 = 76940

Showing the first eight; more decompositions exist.
