Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727922, here are decompositions:

23 + 8727899 = 8727922
113 + 8727809 = 8727922
131 + 8727791 = 8727922
149 + 8727773 = 8727922
191 + 8727731 = 8727922
233 + 8727689 = 8727922
263 + 8727659 = 8727922
311 + 8727611 = 8727922

Showing the first eight; more decompositions exist.
