Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627982, here are decompositions:

5 + 8627977 = 8627982
29 + 8627953 = 8627982
43 + 8627939 = 8627982
71 + 8627911 = 8627982
73 + 8627909 = 8627982
79 + 8627903 = 8627982
89 + 8627893 = 8627982
131 + 8627851 = 8627982

Showing the first eight; more decompositions exist.
