Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726428, here are decompositions:

47 + 8726381 = 8726428
71 + 8726357 = 8726428
401 + 8726027 = 8726428
449 + 8725979 = 8726428
467 + 8725961 = 8726428
479 + 8725949 = 8726428
587 + 8725841 = 8726428
797 + 8725631 = 8726428

Showing the first eight; more decompositions exist.
