Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661694, here are decompositions:

5 + 8661689 = 8661694
11 + 8661683 = 8661694
53 + 8661641 = 8661694
71 + 8661623 = 8661694
113 + 8661581 = 8661694
137 + 8661557 = 8661694
233 + 8661461 = 8661694
257 + 8661437 = 8661694

Showing the first eight; more decompositions exist.
