Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642632, here are decompositions:

41 + 8642591 = 8642632
113 + 8642519 = 8642632
179 + 8642453 = 8642632
443 + 8642189 = 8642632
491 + 8642141 = 8642632
521 + 8642111 = 8642632
569 + 8642063 = 8642632
599 + 8642033 = 8642632

Showing the first eight; more decompositions exist.
