Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611646, here are decompositions:

3 + 8611643 = 8611646
13 + 8611633 = 8611646
73 + 8611573 = 8611646
97 + 8611549 = 8611646
223 + 8611423 = 8611646
349 + 8611297 = 8611646
397 + 8611249 = 8611646
499 + 8611147 = 8611646

Showing the first eight; more decompositions exist.
