Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611626, here are decompositions:

7 + 8611619 = 8611626
13 + 8611613 = 8611626
29 + 8611597 = 8611626
53 + 8611573 = 8611626
97 + 8611529 = 8611626
103 + 8611523 = 8611626
139 + 8611487 = 8611626
193 + 8611433 = 8611626

Showing the first eight; more decompositions exist.
