Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84740, here are decompositions:

3 + 84737 = 84740
43 + 84697 = 84740
67 + 84673 = 84740
109 + 84631 = 84740
151 + 84589 = 84740
181 + 84559 = 84740
241 + 84499 = 84740
277 + 84463 = 84740

Showing the first eight; more decompositions exist.
