Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981924, here are decompositions:

5 + 981919 = 981924
11 + 981913 = 981924
37 + 981887 = 981924
101 + 981823 = 981924
107 + 981817 = 981924
113 + 981811 = 981924
127 + 981797 = 981924
193 + 981731 = 981924

Showing the first eight; more decompositions exist.
