Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687662, here are decompositions:

3 + 8687659 = 8687662
59 + 8687603 = 8687662
149 + 8687513 = 8687662
233 + 8687429 = 8687662
239 + 8687423 = 8687662
281 + 8687381 = 8687662
293 + 8687369 = 8687662
353 + 8687309 = 8687662

Showing the first eight; more decompositions exist.
