Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605900, here are decompositions:

29 + 8605871 = 8605900
47 + 8605853 = 8605900
71 + 8605829 = 8605900
89 + 8605811 = 8605900
167 + 8605733 = 8605900
263 + 8605637 = 8605900
293 + 8605607 = 8605900
389 + 8605511 = 8605900

Showing the first eight; more decompositions exist.
