Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727178, here are decompositions:

17 + 8727161 = 8727178
29 + 8727149 = 8727178
59 + 8727119 = 8727178
191 + 8726987 = 8727178
389 + 8726789 = 8727178
401 + 8726777 = 8727178
419 + 8726759 = 8727178
479 + 8726699 = 8727178

Showing the first eight; more decompositions exist.
