Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137930, here are decompositions:

3 + 137927 = 137930
19 + 137911 = 137930
61 + 137869 = 137930
103 + 137827 = 137930
127 + 137803 = 137930
139 + 137791 = 137930
193 + 137737 = 137930
223 + 137707 = 137930

Showing the first eight; more decompositions exist.
