Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601940, here are decompositions:

3 + 8601937 = 8601940
23 + 8601917 = 8601940
71 + 8601869 = 8601940
167 + 8601773 = 8601940
173 + 8601767 = 8601940
197 + 8601743 = 8601940
233 + 8601707 = 8601940
251 + 8601689 = 8601940

Showing the first eight; more decompositions exist.
