Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137586, here are decompositions:

13 + 137573 = 137586
19 + 137567 = 137586
67 + 137519 = 137586
79 + 137507 = 137586
103 + 137483 = 137586
109 + 137477 = 137586
139 + 137447 = 137586
149 + 137437 = 137586

Showing the first eight; more decompositions exist.
