Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742900, here are decompositions:

13 + 8742887 = 8742900
43 + 8742857 = 8742900
53 + 8742847 = 8742900
79 + 8742821 = 8742900
83 + 8742817 = 8742900
113 + 8742787 = 8742900
211 + 8742689 = 8742900
223 + 8742677 = 8742900

Showing the first eight; more decompositions exist.
