Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137952, here are decompositions:

5 + 137947 = 137952
11 + 137941 = 137952
19 + 137933 = 137952
41 + 137911 = 137952
43 + 137909 = 137952
79 + 137873 = 137952
83 + 137869 = 137952
103 + 137849 = 137952

Showing the first eight; more decompositions exist.
