Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981936, here are decompositions:

17 + 981919 = 981936
23 + 981913 = 981936
47 + 981889 = 981936
113 + 981823 = 981936
127 + 981809 = 981936
139 + 981797 = 981936
167 + 981769 = 981936
223 + 981713 = 981936

Showing the first eight; more decompositions exist.
