Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689378, here are decompositions:

29 + 8689349 = 8689378
59 + 8689319 = 8689378
197 + 8689181 = 8689378
281 + 8689097 = 8689378
569 + 8688809 = 8689378
587 + 8688791 = 8689378
809 + 8688569 = 8689378
821 + 8688557 = 8689378

Showing the first eight; more decompositions exist.
