Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616166, here are decompositions:

17 + 8616149 = 8616166
137 + 8616029 = 8616166
443 + 8615723 = 8616166
509 + 8615657 = 8616166
599 + 8615567 = 8616166
653 + 8615513 = 8616166
659 + 8615507 = 8616166
743 + 8615423 = 8616166

Showing the first eight; more decompositions exist.
