Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137394, here are decompositions:

7 + 137387 = 137394
11 + 137383 = 137394
31 + 137363 = 137394
41 + 137353 = 137394
53 + 137341 = 137394
73 + 137321 = 137394
193 + 137201 = 137394
197 + 137197 = 137394

Showing the first eight; more decompositions exist.
