Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715142, here are decompositions:

83 + 8715059 = 8715142
101 + 8715041 = 8715142
113 + 8715029 = 8715142
131 + 8715011 = 8715142
179 + 8714963 = 8715142
239 + 8714903 = 8715142
269 + 8714873 = 8715142
353 + 8714789 = 8715142

Showing the first eight; more decompositions exist.
