Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699142, here are decompositions:

29 + 8699113 = 8699142
73 + 8699069 = 8699142
79 + 8699063 = 8699142
103 + 8699039 = 8699142
173 + 8698969 = 8699142
181 + 8698961 = 8699142
211 + 8698931 = 8699142
271 + 8698871 = 8699142

Showing the first eight; more decompositions exist.
