Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720630, here are decompositions:

3 + 8720627 = 8720630
7 + 8720623 = 8720630
13 + 8720617 = 8720630
73 + 8720557 = 8720630
97 + 8720533 = 8720630
151 + 8720479 = 8720630
199 + 8720431 = 8720630
223 + 8720407 = 8720630

Showing the first eight; more decompositions exist.
