Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718042, here are decompositions:

29 + 8718013 = 8718042
31 + 8718011 = 8718042
43 + 8717999 = 8718042
61 + 8717981 = 8718042
79 + 8717963 = 8718042
83 + 8717959 = 8718042
103 + 8717939 = 8718042
173 + 8717869 = 8718042

Showing the first eight; more decompositions exist.
