Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599720, here are decompositions:

29 + 8599691 = 8599720
47 + 8599673 = 8599720
53 + 8599667 = 8599720
71 + 8599649 = 8599720
113 + 8599607 = 8599720
131 + 8599589 = 8599720
137 + 8599583 = 8599720
167 + 8599553 = 8599720

Showing the first eight; more decompositions exist.
