Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726578, here are decompositions:

5 + 8726573 = 8726578
71 + 8726507 = 8726578
131 + 8726447 = 8726578
197 + 8726381 = 8726578
227 + 8726351 = 8726578
491 + 8726087 = 8726578
557 + 8726021 = 8726578
587 + 8725991 = 8726578

Showing the first eight; more decompositions exist.
