Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611782, here are decompositions:

59 + 8611723 = 8611782
61 + 8611721 = 8611782
73 + 8611709 = 8611782
79 + 8611703 = 8611782
103 + 8611679 = 8611782
139 + 8611643 = 8611782
149 + 8611633 = 8611782
163 + 8611619 = 8611782

Showing the first eight; more decompositions exist.
