Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76886, here are decompositions:

3 + 76883 = 76886
13 + 76873 = 76886
67 + 76819 = 76886
109 + 76777 = 76886
283 + 76603 = 76886
307 + 76579 = 76886
349 + 76537 = 76886
367 + 76519 = 76886

Showing the first eight; more decompositions exist.
