Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746320, here are decompositions:

17 + 8746303 = 8746320
19 + 8746301 = 8746320
53 + 8746267 = 8746320
59 + 8746261 = 8746320
61 + 8746259 = 8746320
83 + 8746237 = 8746320
97 + 8746223 = 8746320
113 + 8746207 = 8746320

Showing the first eight; more decompositions exist.
