Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715320, here are decompositions:

127 + 8715193 = 8715320
139 + 8715181 = 8715320
241 + 8715079 = 8715320
307 + 8715013 = 8715320
331 + 8714989 = 8715320
337 + 8714983 = 8715320
373 + 8714947 = 8715320
379 + 8714941 = 8715320

Showing the first eight; more decompositions exist.
