Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688662, here are decompositions:

61 + 8688601 = 8688662
79 + 8688583 = 8688662
109 + 8688553 = 8688662
193 + 8688469 = 8688662
313 + 8688349 = 8688662
379 + 8688283 = 8688662
709 + 8687953 = 8688662
733 + 8687929 = 8688662

Showing the first eight; more decompositions exist.
