Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642584, here are decompositions:

3 + 8642581 = 8642584
17 + 8642567 = 8642584
131 + 8642453 = 8642584
281 + 8642303 = 8642584
347 + 8642237 = 8642584
443 + 8642141 = 8642584
521 + 8642063 = 8642584
557 + 8642027 = 8642584

Showing the first eight; more decompositions exist.
