Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683380, here are decompositions:

53 + 8683327 = 8683380
59 + 8683321 = 8683380
61 + 8683319 = 8683380
71 + 8683309 = 8683380
73 + 8683307 = 8683380
127 + 8683253 = 8683380
131 + 8683249 = 8683380
149 + 8683231 = 8683380

Showing the first eight; more decompositions exist.
