Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601424, here are decompositions:

3 + 8601421 = 8601424
23 + 8601401 = 8601424
131 + 8601293 = 8601424
191 + 8601233 = 8601424
233 + 8601191 = 8601424
281 + 8601143 = 8601424
311 + 8601113 = 8601424
317 + 8601107 = 8601424

Showing the first eight; more decompositions exist.
