Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736620, here are decompositions:

3 + 8736617 = 8736620
37 + 8736583 = 8736620
73 + 8736547 = 8736620
157 + 8736463 = 8736620
397 + 8736223 = 8736620
421 + 8736199 = 8736620
433 + 8736187 = 8736620
523 + 8736097 = 8736620

Showing the first eight; more decompositions exist.
