Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721014, here are decompositions:

37 + 8720977 = 8721014
61 + 8720953 = 8721014
67 + 8720947 = 8721014
73 + 8720941 = 8721014
103 + 8720911 = 8721014
241 + 8720773 = 8721014
307 + 8720707 = 8721014
397 + 8720617 = 8721014

Showing the first eight; more decompositions exist.
