Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758890, here are decompositions:

11 + 8758879 = 8758890
13 + 8758877 = 8758890
29 + 8758861 = 8758890
43 + 8758847 = 8758890
67 + 8758823 = 8758890
71 + 8758819 = 8758890
89 + 8758801 = 8758890
97 + 8758793 = 8758890

Showing the first eight; more decompositions exist.
