Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727172, here are decompositions:

11 + 8727161 = 8727172
23 + 8727149 = 8727172
53 + 8727119 = 8727172
59 + 8727113 = 8727172
89 + 8727083 = 8727172
383 + 8726789 = 8727172
449 + 8726723 = 8727172
599 + 8726573 = 8727172

Showing the first eight; more decompositions exist.
