Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981926, here are decompositions:

7 + 981919 = 981926
13 + 981913 = 981926
37 + 981889 = 981926
103 + 981823 = 981926
109 + 981817 = 981926
157 + 981769 = 981926
223 + 981703 = 981926
229 + 981697 = 981926

Showing the first eight; more decompositions exist.
