Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611738, here are decompositions:

17 + 8611721 = 8611738
29 + 8611709 = 8611738
41 + 8611697 = 8611738
59 + 8611679 = 8611738
71 + 8611667 = 8611738
137 + 8611601 = 8611738
251 + 8611487 = 8611738
389 + 8611349 = 8611738

Showing the first eight; more decompositions exist.
