Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721852, here are decompositions:

79 + 8721773 = 8721852
89 + 8721763 = 8721852
103 + 8721749 = 8721852
151 + 8721701 = 8721852
179 + 8721673 = 8721852
311 + 8721541 = 8721852
313 + 8721539 = 8721852
353 + 8721499 = 8721852

Showing the first eight; more decompositions exist.
