Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137898, here are decompositions:

29 + 137869 = 137898
31 + 137867 = 137898
67 + 137831 = 137898
71 + 137827 = 137898
107 + 137791 = 137898
127 + 137771 = 137898
191 + 137707 = 137898
199 + 137699 = 137898

Showing the first eight; more decompositions exist.
