Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601942, here are decompositions:

5 + 8601937 = 8601942
59 + 8601883 = 8601942
73 + 8601869 = 8601942
199 + 8601743 = 8601942
311 + 8601631 = 8601942
313 + 8601629 = 8601942
373 + 8601569 = 8601942
431 + 8601511 = 8601942

Showing the first eight; more decompositions exist.
