Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84520, here are decompositions:

11 + 84509 = 84520
17 + 84503 = 84520
53 + 84467 = 84520
71 + 84449 = 84520
83 + 84437 = 84520
89 + 84431 = 84520
113 + 84407 = 84520
131 + 84389 = 84520

Showing the first eight; more decompositions exist.
