Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675420, here are decompositions:

7 + 8675413 = 8675420
37 + 8675383 = 8675420
43 + 8675377 = 8675420
79 + 8675341 = 8675420
97 + 8675323 = 8675420
109 + 8675311 = 8675420
199 + 8675221 = 8675420
223 + 8675197 = 8675420

Showing the first eight; more decompositions exist.
