Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705684, here are decompositions:

3 + 8705681 = 8705684
67 + 8705617 = 8705684
73 + 8705611 = 8705684
157 + 8705527 = 8705684
193 + 8705491 = 8705684
223 + 8705461 = 8705684
241 + 8705443 = 8705684
373 + 8705311 = 8705684

Showing the first eight; more decompositions exist.
