Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726782, here are decompositions:

5 + 8726777 = 8726782
23 + 8726759 = 8726782
59 + 8726723 = 8726782
83 + 8726699 = 8726782
149 + 8726633 = 8726782
401 + 8726381 = 8726782
419 + 8726363 = 8726782
431 + 8726351 = 8726782

Showing the first eight; more decompositions exist.
