Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608720, here are decompositions:

47 + 8608673 = 8608720
53 + 8608667 = 8608720
101 + 8608619 = 8608720
137 + 8608583 = 8608720
149 + 8608571 = 8608720
167 + 8608553 = 8608720
191 + 8608529 = 8608720
233 + 8608487 = 8608720

Showing the first eight; more decompositions exist.
