Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726812, here are decompositions:

11 + 8726801 = 8726812
23 + 8726789 = 8726812
53 + 8726759 = 8726812
89 + 8726723 = 8726812
113 + 8726699 = 8726812
179 + 8726633 = 8726812
239 + 8726573 = 8726812
431 + 8726381 = 8726812

Showing the first eight; more decompositions exist.
