Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979686, here are decompositions:

137 + 979549 = 979686
157 + 979529 = 979686
167 + 979519 = 979686
229 + 979457 = 979686
263 + 979423 = 979686
283 + 979403 = 979686
307 + 979379 = 979686
313 + 979373 = 979686

Showing the first eight; more decompositions exist.
