Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607178, here are decompositions:

5 + 8607173 = 8607178
11 + 8607167 = 8607178
101 + 8607077 = 8607178
149 + 8607029 = 8607178
179 + 8606999 = 8607178
269 + 8606909 = 8607178
389 + 8606789 = 8607178
449 + 8606729 = 8607178

Showing the first eight; more decompositions exist.
