Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137976, here are decompositions:

19 + 137957 = 137976
29 + 137947 = 137976
43 + 137933 = 137976
67 + 137909 = 137976
103 + 137873 = 137976
107 + 137869 = 137976
109 + 137867 = 137976
127 + 137849 = 137976

Showing the first eight; more decompositions exist.
