Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718356, here are decompositions:

7 + 8718349 = 8718356
13 + 8718343 = 8718356
43 + 8718313 = 8718356
79 + 8718277 = 8718356
109 + 8718247 = 8718356
139 + 8718217 = 8718356
193 + 8718163 = 8718356
313 + 8718043 = 8718356

Showing the first eight; more decompositions exist.
