Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662646, here are decompositions:

67 + 8662579 = 8662646
163 + 8662483 = 8662646
193 + 8662453 = 8662646
199 + 8662447 = 8662646
367 + 8662279 = 8662646
373 + 8662273 = 8662646
397 + 8662249 = 8662646
457 + 8662189 = 8662646

Showing the first eight; more decompositions exist.
