Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613998, here are decompositions:

31 + 8613967 = 8613998
37 + 8613961 = 8613998
181 + 8613817 = 8613998
241 + 8613757 = 8613998
439 + 8613559 = 8613998
541 + 8613457 = 8613998
571 + 8613427 = 8613998
577 + 8613421 = 8613998

Showing the first eight; more decompositions exist.
