Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137946, here are decompositions:

5 + 137941 = 137946
13 + 137933 = 137946
19 + 137927 = 137946
37 + 137909 = 137946
73 + 137873 = 137946
79 + 137867 = 137946
97 + 137849 = 137946
223 + 137723 = 137946

Showing the first eight; more decompositions exist.
