Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613398, here are decompositions:

7 + 8613391 = 8613398
19 + 8613379 = 8613398
271 + 8613127 = 8613398
307 + 8613091 = 8613398
379 + 8613019 = 8613398
397 + 8613001 = 8613398
439 + 8612959 = 8613398
457 + 8612941 = 8613398

Showing the first eight; more decompositions exist.
