Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657982, here are decompositions:

13 + 8657969 = 8657982
59 + 8657923 = 8657982
79 + 8657903 = 8657982
101 + 8657881 = 8657982
131 + 8657851 = 8657982
149 + 8657833 = 8657982
181 + 8657801 = 8657982
199 + 8657783 = 8657982

Showing the first eight; more decompositions exist.
