Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688002, here are decompositions:

19 + 8687983 = 8688002
73 + 8687929 = 8688002
79 + 8687923 = 8688002
331 + 8687671 = 8688002
523 + 8687479 = 8688002
541 + 8687461 = 8688002
601 + 8687401 = 8688002
619 + 8687383 = 8688002

Showing the first eight; more decompositions exist.
