Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137738, here are decompositions:

31 + 137707 = 137738
79 + 137659 = 137738
151 + 137587 = 137738
379 + 137359 = 137738
397 + 137341 = 137738
487 + 137251 = 137738
499 + 137239 = 137738
541 + 137197 = 137738

Showing the first eight; more decompositions exist.
