Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653380, here are decompositions:

7 + 8653373 = 8653380
19 + 8653361 = 8653380
37 + 8653343 = 8653380
53 + 8653327 = 8653380
61 + 8653319 = 8653380
83 + 8653297 = 8653380
97 + 8653283 = 8653380
101 + 8653279 = 8653380

Showing the first eight; more decompositions exist.
