Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747018, here are decompositions:

19 + 8746999 = 8747018
61 + 8746957 = 8747018
79 + 8746939 = 8747018
97 + 8746921 = 8747018
139 + 8746879 = 8747018
157 + 8746861 = 8747018
199 + 8746819 = 8747018
211 + 8746807 = 8747018

Showing the first eight; more decompositions exist.
