Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719874, here are decompositions:

43 + 8719831 = 8719874
61 + 8719813 = 8719874
73 + 8719801 = 8719874
103 + 8719771 = 8719874
127 + 8719747 = 8719874
193 + 8719681 = 8719874
211 + 8719663 = 8719874
271 + 8719603 = 8719874

Showing the first eight; more decompositions exist.
