Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699660, here are decompositions:

19 + 8699641 = 8699660
103 + 8699557 = 8699660
127 + 8699533 = 8699660
241 + 8699419 = 8699660
271 + 8699389 = 8699660
349 + 8699311 = 8699660
367 + 8699293 = 8699660
397 + 8699263 = 8699660

Showing the first eight; more decompositions exist.
