Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736870, here are decompositions:

17 + 8736853 = 8736870
53 + 8736817 = 8736870
61 + 8736809 = 8736870
71 + 8736799 = 8736870
83 + 8736787 = 8736870
89 + 8736781 = 8736870
151 + 8736719 = 8736870
167 + 8736703 = 8736870

Showing the first eight; more decompositions exist.
