Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84538, here are decompositions:

5 + 84533 = 84538
17 + 84521 = 84538
29 + 84509 = 84538
71 + 84467 = 84538
89 + 84449 = 84538
101 + 84437 = 84538
107 + 84431 = 84538
131 + 84407 = 84538

Showing the first eight; more decompositions exist.
