Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705998, here are decompositions:

29 + 8705969 = 8705998
137 + 8705861 = 8705998
167 + 8705831 = 8705998
239 + 8705759 = 8705998
251 + 8705747 = 8705998
269 + 8705729 = 8705998
317 + 8705681 = 8705998
359 + 8705639 = 8705998

Showing the first eight; more decompositions exist.
