Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84540, here are decompositions:

7 + 84533 = 84540
17 + 84523 = 84540
19 + 84521 = 84540
31 + 84509 = 84540
37 + 84503 = 84540
41 + 84499 = 84540
59 + 84481 = 84540
73 + 84467 = 84540

Showing the first eight; more decompositions exist.
