Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603420, here are decompositions:

13 + 8603407 = 8603420
31 + 8603389 = 8603420
73 + 8603347 = 8603420
79 + 8603341 = 8603420
127 + 8603293 = 8603420
157 + 8603263 = 8603420
181 + 8603239 = 8603420
283 + 8603137 = 8603420

Showing the first eight; more decompositions exist.
