Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137966, here are decompositions:

19 + 137947 = 137966
97 + 137869 = 137966
139 + 137827 = 137966
163 + 137803 = 137966
223 + 137743 = 137966
229 + 137737 = 137966
307 + 137659 = 137966
313 + 137653 = 137966

Showing the first eight; more decompositions exist.
