Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601442, here are decompositions:

41 + 8601401 = 8601442
53 + 8601389 = 8601442
149 + 8601293 = 8601442
233 + 8601209 = 8601442
251 + 8601191 = 8601442
359 + 8601083 = 8601442
653 + 8600789 = 8601442
659 + 8600783 = 8601442

Showing the first eight; more decompositions exist.
