Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721074, here are decompositions:

13 + 8721061 = 8721074
31 + 8721043 = 8721074
97 + 8720977 = 8721074
127 + 8720947 = 8721074
163 + 8720911 = 8721074
277 + 8720797 = 8721074
367 + 8720707 = 8721074
457 + 8720617 = 8721074

Showing the first eight; more decompositions exist.
