Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706890, here are decompositions:

19 + 8706871 = 8706890
37 + 8706853 = 8706890
61 + 8706829 = 8706890
67 + 8706823 = 8706890
97 + 8706793 = 8706890
139 + 8706751 = 8706890
163 + 8706727 = 8706890
223 + 8706667 = 8706890

Showing the first eight; more decompositions exist.
