Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137994, here are decompositions:

11 + 137983 = 137994
37 + 137957 = 137994
47 + 137947 = 137994
53 + 137941 = 137994
61 + 137933 = 137994
67 + 137927 = 137994
83 + 137911 = 137994
127 + 137867 = 137994

Showing the first eight; more decompositions exist.
