Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718142, here are decompositions:

29 + 8718113 = 8718142
53 + 8718089 = 8718142
131 + 8718011 = 8718142
149 + 8717993 = 8718142
179 + 8717963 = 8718142
233 + 8717909 = 8718142
269 + 8717873 = 8718142
281 + 8717861 = 8718142

Showing the first eight; more decompositions exist.
