Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981882, here are decompositions:

59 + 981823 = 981882
71 + 981811 = 981882
73 + 981809 = 981882
113 + 981769 = 981882
151 + 981731 = 981882
179 + 981703 = 981882
191 + 981691 = 981882
199 + 981683 = 981882

Showing the first eight; more decompositions exist.
