Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687732, here are decompositions:

3 + 8687729 = 8687732
19 + 8687713 = 8687732
61 + 8687671 = 8687732
73 + 8687659 = 8687732
211 + 8687521 = 8687732
271 + 8687461 = 8687732
331 + 8687401 = 8687732
349 + 8687383 = 8687732

Showing the first eight; more decompositions exist.
