Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689942, here are decompositions:

89 + 8689853 = 8689942
101 + 8689841 = 8689942
269 + 8689673 = 8689942
281 + 8689661 = 8689942
293 + 8689649 = 8689942
389 + 8689553 = 8689942
449 + 8689493 = 8689942
461 + 8689481 = 8689942

Showing the first eight; more decompositions exist.
