Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642618, here are decompositions:

37 + 8642581 = 8642618
109 + 8642509 = 8642618
151 + 8642467 = 8642618
337 + 8642281 = 8642618
421 + 8642197 = 8642618
499 + 8642119 = 8642618
541 + 8642077 = 8642618
631 + 8641987 = 8642618

Showing the first eight; more decompositions exist.
