Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708666, here are decompositions:

3 + 8708663 = 8708666
139 + 8708527 = 8708666
157 + 8708509 = 8708666
397 + 8708269 = 8708666
523 + 8708143 = 8708666
727 + 8707939 = 8708666
787 + 8707879 = 8708666
823 + 8707843 = 8708666

Showing the first eight; more decompositions exist.
