Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726818, here are decompositions:

17 + 8726801 = 8726818
29 + 8726789 = 8726818
41 + 8726777 = 8726818
59 + 8726759 = 8726818
131 + 8726687 = 8726818
311 + 8726507 = 8726818
461 + 8726357 = 8726818
467 + 8726351 = 8726818

Showing the first eight; more decompositions exist.
