Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601488, here are decompositions:

31 + 8601457 = 8601488
67 + 8601421 = 8601488
97 + 8601391 = 8601488
127 + 8601361 = 8601488
157 + 8601331 = 8601488
199 + 8601289 = 8601488
211 + 8601277 = 8601488
331 + 8601157 = 8601488

Showing the first eight; more decompositions exist.
