Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685842, here are decompositions:

73 + 8685769 = 8685842
79 + 8685763 = 8685842
103 + 8685739 = 8685842
181 + 8685661 = 8685842
211 + 8685631 = 8685842
223 + 8685619 = 8685842
241 + 8685601 = 8685842
271 + 8685571 = 8685842

Showing the first eight; more decompositions exist.
