Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981896, here are decompositions:

7 + 981889 = 981896
73 + 981823 = 981896
79 + 981817 = 981896
127 + 981769 = 981896
193 + 981703 = 981896
199 + 981697 = 981896
373 + 981523 = 981896
379 + 981517 = 981896

Showing the first eight; more decompositions exist.
