Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121906, here are decompositions:

17 + 121889 = 121906
23 + 121883 = 121906
53 + 121853 = 121906
179 + 121727 = 121906
269 + 121637 = 121906
347 + 121559 = 121906
353 + 121553 = 121906
359 + 121547 = 121906

Showing the first eight; more decompositions exist.
