Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689958, here are decompositions:

181 + 8689777 = 8689958
229 + 8689729 = 8689958
271 + 8689687 = 8689958
331 + 8689627 = 8689958
349 + 8689609 = 8689958
367 + 8689591 = 8689958
421 + 8689537 = 8689958
709 + 8689249 = 8689958

Showing the first eight; more decompositions exist.
