Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715722, here are decompositions:

3 + 8715719 = 8715722
13 + 8715709 = 8715722
19 + 8715703 = 8715722
73 + 8715649 = 8715722
163 + 8715559 = 8715722
199 + 8715523 = 8715722
271 + 8715451 = 8715722
313 + 8715409 = 8715722

Showing the first eight; more decompositions exist.
