Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642446, here are decompositions:

17 + 8642429 = 8642446
257 + 8642189 = 8642446
347 + 8642099 = 8642446
383 + 8642063 = 8642446
389 + 8642057 = 8642446
419 + 8642027 = 8642446
443 + 8642003 = 8642446
563 + 8641883 = 8642446

Showing the first eight; more decompositions exist.
