Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717982, here are decompositions:

19 + 8717963 = 8717982
23 + 8717959 = 8717982
43 + 8717939 = 8717982
73 + 8717909 = 8717982
101 + 8717881 = 8717982
109 + 8717873 = 8717982
113 + 8717869 = 8717982
139 + 8717843 = 8717982

Showing the first eight; more decompositions exist.
