Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607442, here are decompositions:

29 + 8607413 = 8607442
59 + 8607383 = 8607442
71 + 8607371 = 8607442
101 + 8607341 = 8607442
113 + 8607329 = 8607442
149 + 8607293 = 8607442
251 + 8607191 = 8607442
269 + 8607173 = 8607442

Showing the first eight; more decompositions exist.
