Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743620, here are decompositions:

23 + 8743597 = 8743620
31 + 8743589 = 8743620
37 + 8743583 = 8743620
59 + 8743561 = 8743620
71 + 8743549 = 8743620
73 + 8743547 = 8743620
89 + 8743531 = 8743620
107 + 8743513 = 8743620

Showing the first eight; more decompositions exist.
