Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601386, here are decompositions:

43 + 8601343 = 8601386
97 + 8601289 = 8601386
109 + 8601277 = 8601386
223 + 8601163 = 8601386
229 + 8601157 = 8601386
349 + 8601037 = 8601386
373 + 8601013 = 8601386
439 + 8600947 = 8601386

Showing the first eight; more decompositions exist.
