Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605402, here are decompositions:

23 + 8605379 = 8605402
41 + 8605361 = 8605402
83 + 8605319 = 8605402
173 + 8605229 = 8605402
191 + 8605211 = 8605402
233 + 8605169 = 8605402
383 + 8605019 = 8605402
401 + 8605001 = 8605402

Showing the first eight; more decompositions exist.
