Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611216, here are decompositions:

83 + 8611133 = 8611216
179 + 8611037 = 8611216
353 + 8610863 = 8611216
389 + 8610827 = 8611216
479 + 8610737 = 8611216
557 + 8610659 = 8611216
599 + 8610617 = 8611216
617 + 8610599 = 8611216

Showing the first eight; more decompositions exist.
