Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981598, here are decompositions:

11 + 981587 = 981598
29 + 981569 = 981598
71 + 981527 = 981598
131 + 981467 = 981598
179 + 981419 = 981598
311 + 981287 = 981598
389 + 981209 = 981598
461 + 981137 = 981598

Showing the first eight; more decompositions exist.
