Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727100, here are decompositions:

17 + 8727083 = 8727100
47 + 8727053 = 8727100
113 + 8726987 = 8727100
131 + 8726969 = 8727100
227 + 8726873 = 8727100
251 + 8726849 = 8727100
311 + 8726789 = 8727100
401 + 8726699 = 8727100

Showing the first eight; more decompositions exist.
