Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689142, here are decompositions:

13 + 8689129 = 8689142
31 + 8689111 = 8689142
73 + 8689069 = 8689142
79 + 8689063 = 8689142
103 + 8689039 = 8689142
109 + 8689033 = 8689142
151 + 8688991 = 8689142
181 + 8688961 = 8689142

Showing the first eight; more decompositions exist.
