Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720534, here are decompositions:

3 + 8720531 = 8720534
37 + 8720497 = 8720534
103 + 8720431 = 8720534
127 + 8720407 = 8720534
223 + 8720311 = 8720534
307 + 8720227 = 8720534
373 + 8720161 = 8720534
397 + 8720137 = 8720534

Showing the first eight; more decompositions exist.
