Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689748, here are decompositions:

19 + 8689729 = 8689748
37 + 8689711 = 8689748
61 + 8689687 = 8689748
139 + 8689609 = 8689748
157 + 8689591 = 8689748
211 + 8689537 = 8689748
349 + 8689399 = 8689748
439 + 8689309 = 8689748

Showing the first eight; more decompositions exist.
