Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617580, here are decompositions:

19 + 8617561 = 8617580
31 + 8617549 = 8617580
61 + 8617519 = 8617580
67 + 8617513 = 8617580
163 + 8617417 = 8617580
199 + 8617381 = 8617580
373 + 8617207 = 8617580
379 + 8617201 = 8617580

Showing the first eight; more decompositions exist.
