Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601728, here are decompositions:

61 + 8601667 = 8601728
97 + 8601631 = 8601728
229 + 8601499 = 8601728
271 + 8601457 = 8601728
307 + 8601421 = 8601728
337 + 8601391 = 8601728
367 + 8601361 = 8601728
397 + 8601331 = 8601728

Showing the first eight; more decompositions exist.
