Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699140, here are decompositions:

71 + 8699069 = 8699140
89 + 8699051 = 8699140
101 + 8699039 = 8699140
167 + 8698973 = 8699140
179 + 8698961 = 8699140
251 + 8698889 = 8699140
269 + 8698871 = 8699140
353 + 8698787 = 8699140

Showing the first eight; more decompositions exist.
