Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699684, here are decompositions:

43 + 8699641 = 8699684
73 + 8699611 = 8699684
127 + 8699557 = 8699684
151 + 8699533 = 8699684
241 + 8699443 = 8699684
271 + 8699413 = 8699684
373 + 8699311 = 8699684
421 + 8699263 = 8699684

Showing the first eight; more decompositions exist.
