Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659874, here are decompositions:

7 + 8659867 = 8659874
37 + 8659837 = 8659874
127 + 8659747 = 8659874
163 + 8659711 = 8659874
211 + 8659663 = 8659874
331 + 8659543 = 8659874
337 + 8659537 = 8659874
373 + 8659501 = 8659874

Showing the first eight; more decompositions exist.
