Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727722, here are decompositions:

79 + 8727643 = 8727722
103 + 8727619 = 8727722
139 + 8727583 = 8727722
193 + 8727529 = 8727722
229 + 8727493 = 8727722
271 + 8727451 = 8727722
373 + 8727349 = 8727722
379 + 8727343 = 8727722

Showing the first eight; more decompositions exist.
