Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642366, here are decompositions:

37 + 8642329 = 8642366
193 + 8642173 = 8642366
307 + 8642059 = 8642366
379 + 8641987 = 8642366
409 + 8641957 = 8642366
457 + 8641909 = 8642366
547 + 8641819 = 8642366
619 + 8641747 = 8642366

Showing the first eight; more decompositions exist.
