Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675868, here are decompositions:

7 + 8675861 = 8675868
11 + 8675857 = 8675868
29 + 8675839 = 8675868
101 + 8675767 = 8675868
191 + 8675677 = 8675868
197 + 8675671 = 8675868
277 + 8675591 = 8675868
347 + 8675521 = 8675868

Showing the first eight; more decompositions exist.
