Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758920, here are decompositions:

17 + 8758903 = 8758920
19 + 8758901 = 8758920
29 + 8758891 = 8758920
31 + 8758889 = 8758920
41 + 8758879 = 8758920
43 + 8758877 = 8758920
59 + 8758861 = 8758920
73 + 8758847 = 8758920

Showing the first eight; more decompositions exist.
