Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981592, here are decompositions:

5 + 981587 = 981592
23 + 981569 = 981592
149 + 981443 = 981592
173 + 981419 = 981592
281 + 981311 = 981592
383 + 981209 = 981592
419 + 981173 = 981592
569 + 981023 = 981592

Showing the first eight; more decompositions exist.
