Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597720, here are decompositions:

13 + 8597707 = 8597720
37 + 8597683 = 8597720
73 + 8597647 = 8597720
97 + 8597623 = 8597720
193 + 8597527 = 8597720
199 + 8597521 = 8597720
349 + 8597371 = 8597720
367 + 8597353 = 8597720

Showing the first eight; more decompositions exist.
