Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758830, here are decompositions:

7 + 8758823 = 8758830
11 + 8758819 = 8758830
29 + 8758801 = 8758830
37 + 8758793 = 8758830
43 + 8758787 = 8758830
53 + 8758777 = 8758830
83 + 8758747 = 8758830
97 + 8758733 = 8758830

Showing the first eight; more decompositions exist.
