Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726486, here are decompositions:

7 + 8726479 = 8726486
19 + 8726467 = 8726486
37 + 8726449 = 8726486
103 + 8726383 = 8726486
127 + 8726359 = 8726486
157 + 8726329 = 8726486
163 + 8726323 = 8726486
229 + 8726257 = 8726486

Showing the first eight; more decompositions exist.
