Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611722, here are decompositions:

13 + 8611709 = 8611722
19 + 8611703 = 8611722
43 + 8611679 = 8611722
59 + 8611663 = 8611722
79 + 8611643 = 8611722
89 + 8611633 = 8611722
103 + 8611619 = 8611722
109 + 8611613 = 8611722

Showing the first eight; more decompositions exist.
