Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715122, here are decompositions:

19 + 8715103 = 8715122
43 + 8715079 = 8715122
103 + 8715019 = 8715122
109 + 8715013 = 8715122
139 + 8714983 = 8715122
181 + 8714941 = 8715122
349 + 8714773 = 8715122
379 + 8714743 = 8715122

Showing the first eight; more decompositions exist.
