Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981832, here are decompositions:

23 + 981809 = 981832
101 + 981731 = 981832
149 + 981683 = 981832
179 + 981653 = 981832
233 + 981599 = 981832
263 + 981569 = 981832
359 + 981473 = 981832
389 + 981443 = 981832

Showing the first eight; more decompositions exist.
