Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137964, here are decompositions:

7 + 137957 = 137964
17 + 137947 = 137964
23 + 137941 = 137964
31 + 137933 = 137964
37 + 137927 = 137964
53 + 137911 = 137964
97 + 137867 = 137964
137 + 137827 = 137964

Showing the first eight; more decompositions exist.
