Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601538, here are decompositions:

47 + 8601491 = 8601538
89 + 8601449 = 8601538
137 + 8601401 = 8601538
149 + 8601389 = 8601538
347 + 8601191 = 8601538
431 + 8601107 = 8601538
461 + 8601077 = 8601538
509 + 8601029 = 8601538

Showing the first eight; more decompositions exist.
