Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611620, here are decompositions:

7 + 8611613 = 8611620
19 + 8611601 = 8611620
23 + 8611597 = 8611620
47 + 8611573 = 8611620
71 + 8611549 = 8611620
89 + 8611531 = 8611620
97 + 8611523 = 8611620
179 + 8611441 = 8611620

Showing the first eight; more decompositions exist.
