Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981956, here are decompositions:

7 + 981949 = 981956
37 + 981919 = 981956
43 + 981913 = 981956
67 + 981889 = 981956
139 + 981817 = 981956
379 + 981577 = 981956
433 + 981523 = 981956
439 + 981517 = 981956

Showing the first eight; more decompositions exist.
