Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137532, here are decompositions:

13 + 137519 = 137532
41 + 137491 = 137532
79 + 137453 = 137532
89 + 137443 = 137532
139 + 137393 = 137532
149 + 137383 = 137532
163 + 137369 = 137532
173 + 137359 = 137532

Showing the first eight; more decompositions exist.
