Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84618, here are decompositions:

29 + 84589 = 84618
59 + 84559 = 84618
67 + 84551 = 84618
97 + 84521 = 84618
109 + 84509 = 84618
137 + 84481 = 84618
151 + 84467 = 84618
181 + 84437 = 84618

Showing the first eight; more decompositions exist.
