Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751636, here are decompositions:

7 + 8751629 = 8751636
17 + 8751619 = 8751636
37 + 8751599 = 8751636
43 + 8751593 = 8751636
59 + 8751577 = 8751636
73 + 8751563 = 8751636
79 + 8751557 = 8751636
109 + 8751527 = 8751636

Showing the first eight; more decompositions exist.
