Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616542, here are decompositions:

43 + 8616499 = 8616542
163 + 8616379 = 8616542
223 + 8616319 = 8616542
271 + 8616271 = 8616542
373 + 8616169 = 8616542
499 + 8616043 = 8616542
523 + 8616019 = 8616542
601 + 8615941 = 8616542

Showing the first eight; more decompositions exist.
