Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726558, here are decompositions:

31 + 8726527 = 8726558
37 + 8726521 = 8726558
79 + 8726479 = 8726558
97 + 8726461 = 8726558
109 + 8726449 = 8726558
157 + 8726401 = 8726558
199 + 8726359 = 8726558
229 + 8726329 = 8726558

Showing the first eight; more decompositions exist.
