Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621598, here are decompositions:

17 + 8621581 = 8621598
47 + 8621551 = 8621598
107 + 8621491 = 8621598
131 + 8621467 = 8621598
317 + 8621281 = 8621598
389 + 8621209 = 8621598
397 + 8621201 = 8621598
409 + 8621189 = 8621598

Showing the first eight; more decompositions exist.
