Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658662, here are decompositions:

3 + 8658659 = 8658662
43 + 8658619 = 8658662
73 + 8658589 = 8658662
79 + 8658583 = 8658662
109 + 8658553 = 8658662
193 + 8658469 = 8658662
349 + 8658313 = 8658662
373 + 8658289 = 8658662

Showing the first eight; more decompositions exist.
