Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720606, here are decompositions:

73 + 8720533 = 8720606
109 + 8720497 = 8720606
127 + 8720479 = 8720606
199 + 8720407 = 8720606
373 + 8720233 = 8720606
379 + 8720227 = 8720606
487 + 8720119 = 8720606
607 + 8719999 = 8720606

Showing the first eight; more decompositions exist.
