Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702874, here are decompositions:

31 + 8702843 = 8702874
41 + 8702833 = 8702874
53 + 8702821 = 8702874
71 + 8702803 = 8702874
97 + 8702777 = 8702874
127 + 8702747 = 8702874
181 + 8702693 = 8702874
211 + 8702663 = 8702874

Showing the first eight; more decompositions exist.
