Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726530, here are decompositions:

3 + 8726527 = 8726530
23 + 8726507 = 8726530
83 + 8726447 = 8726530
149 + 8726381 = 8726530
167 + 8726363 = 8726530
173 + 8726357 = 8726530
179 + 8726351 = 8726530
257 + 8726273 = 8726530

Showing the first eight; more decompositions exist.
